RHg2
RHg2 is not a term with a single, universally accepted meaning in established scientific literature. In chemistry, it might be encountered as an informal shorthand for a mercury-containing organometallic species in which a single organic substituent R is associated with a diatomic or dinuclear Hg center. However, this usage is not standard, and there is no widely agreed-upon structure or oxidation state for RHg2. More common organomercury classifications include dialkylmercury (R2Hg) and various HgR2-type complexes, with precise bonding and geometry defined by the specific ligands and synthesis.
Because RHg2 is not a standardized designation, any structural interpretation largely depends on the experimental context,
In other uses, RHg2 could appear as a project code, dataset identifier, or fictional designation in literature
