Identity and charge resolution Resolve what the registered anion name denotes before assigning substance properties.
Registry name provenance
Trace the anion wording to the records and structures behind it.
Label-structure conflict
The inspected Wikidata record uses the anion label while listing methylrhenium(VII) trioxide aliases and a SMILES without explicit negative charge; this establishes a record inconsistency, not an anion identity. [Wikidata Q408705](https://www.wikidata.org/wiki/Q408705)
- Which original registry import or source introduced the word 'anion'? provenance
- Does the intended entry denote neutral methylrhenium trioxide, a specific anion or an unresolved source label? definition
Charge and connectivity
Specify the chemical distinctions that an anion assignment must satisfy.
Explicit species assignment
Require composition, connectivity and net charge together; treat [CH3ReO3]− as a candidate to investigate rather than an established identity.
- What experimental evidence establishes negative charge and a retained methyl-rhenium bond? measurement
- Does the reported species preserve CH3ReO3 composition or instead involve hydrogen loss, additional ligands or fragmentation? boundary
Structural and electronic evidence Organize measurements needed to discriminate the proposed anion from chemically adjacent assignments.
Analytical discrimination
Connect ion signals and structural measurements to competing interpretations.
Orthogonal identification
Assess mass, isotope pattern and available spectroscopic or structural evidence without treating any unreported signature as known.
- What measured mass-to-charge ratio, isotope pattern and charge-state evidence support the proposed composition? measurement
- Which independent measurement distinguishes that assignment from an adduct, fragment or neutral precursor? measurement
Electron count and spin
Keep formal electronic bookkeeping separate from measured electronic behavior.
Electronic state support
Record oxidation-state and spin assignments with their assumptions, distinguishing calculations from observations.
- Which ligand-charge assumptions support the proposed rhenium oxidation state? definition
- What magnetic, spectroscopic or computational evidence supports the assigned spin and location of added electron density? measurement
Environment and species persistence Describe where the assigned anion occurs and how its identity changes with conditions.
Formation and observation
Connect the species assignment to its precursor and observation environment.
Sample versus instrument origin
Separate presence in the starting material from generation during ionization or another measurement step.
- Was the proposed anion present before measurement or generated inside the instrument? provenance
- Which precursor, solvent, temperature and charge-generation conditions accompanied its observation? measurement
Association and transformation
Track counterions, persistence and evidence of conversion to other rhenium species.
Conditional stability
Represent persistence as a condition-dependent observation and identify products only where supported.
- What counterion or charge-balancing environment accompanies the species, and is ion pairing established? boundary
- Over what observation period and conditions does the assigned species persist, and which transformation products are confirmed? measurement
Material properties and use Determine which sample properties, identifiers and handling decisions apply to the resolved entity.
Sample composition and constants
Attach purity and physical measurements to the tested salt, solution or other material form.
Property attribution
Distinguish species-level observations from bulk properties of a sample containing the species.
- What fraction of the sample is assigned to the anion, and how are neutral precursor and other rhenium species quantified? measurement
- Do reported thermal, solubility or other constants describe an identified salt, a mixture or neutral methylrhenium trioxide? boundary
Identifiers, hazards and actions
Evaluate identity-specific documentation before applying storage, exposure or use decisions.
Applicable documentation
Require exact-material support for regulatory identifiers, hazard classifications and demonstrated uses; retain missing evidence explicitly.
- Which CAS, PubChem, EC or safety records explicitly describe the resolved charged species or its identified salt? provenance
- What handling restrictions or proposed uses are supported for this material under the intended conditions? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence

What it is Filled
Methylrhenium trioxide anion provisionally denotes the molecular anion [CH3ReO3]−, formally obtained by adding one electron to neutral methylrhenium trioxide.
In scope
- Resolution of the anion label against charge-explicit structures and original records
- Evidence for methyl-rhenium connectivity, oxygen coordination and electronic state
- Conditions under which the assigned species is observed or maintained
- Composition, counterions and impurities of samples containing the species
- Applicability of physical properties, hazard information and regulatory identifiers
Out of scope
- A complete model of neutral methylrhenium trioxide as a separate substance
- Perrhenate and other rhenium oxoanions lacking the assigned methyl connectivity
- Independent models of counterions, solvents and supporting electrolytes
- Commercial formulations and laboratory equipment
- Complete catalytic processes or synthesis protocols
Why it exists Filled
Enable an agent to resolve the identity of the registered methylrhenium trioxide anion, assess evidence for its charge and chemical state, and determine which properties and actions are justified.
Distinguishing features Filled
- Require explicit evidence of negative net charge; the word 'anion' and an elemental formula alone do not establish ionic identity.
- Test whether the species retains a carbon-rhenium bond rather than merely containing methyl-bearing solvent or an associated organic counterion.
- Resolve hydrogen and oxygen counts to distinguish electron attachment from deprotonation, ligand addition or fragmentation.
- Distinguish an ion observed during instrumental analysis from an independently established species in the original sample.
- Check identifier structures before reuse: the registry label must not automatically inherit the properties of neutral methylrhenium trioxide.
What robots and AI may and may not do Filled
Must not
- Present the anion as an isolated, commercially available substance.
- Transfer hazard or property data from the neutral compound without saying so.
- Invent structural or spectroscopic data that has not been reported.
Only with a human decision
- Approving experimental work with organorhenium reagents.
May
- Describe the anion as a provisional or computational species related to methylrhenium trioxide.
- Point users to the neutral compound's record where that is what they need.
Moral aspects Filled
- A clear record of what has and has not been characterised prevents false confidence in the literature.
Who is affected
- Researchers relying on the record
- Database curators
Owners Filled
Steward
Nobody owns the species; the researchers who report it answer for their data.

Standards and interfaces not applicable Not applicable
Not applicable
No species-specific standard or official classification can be confidently assigned to this provisionally identified anion.
Context of use required Filled
- This provisional designation is relevant to research records concerning the electronic structure or reduction chemistry of methylrhenium trioxide.
- Its use in interpreting calculations or analytical observations requires evidence that the species carries the stated negative charge.
