摘要
The title compound, [Co6Hg2(C5H5)6(C5H4Se)6](PF6)4·2CH3CN or [Hg2(CcSe)6][PF6]4·2CH3CN (Cc = C10H9Co), was obtained as bright-orange needle-shaped crystals. It is a salt containing a tetra­cationic dimercury species with six cobaltoceniumseleno­late ligands, four hexa­fluorido­phosphate counter-ions and two aceto­nitrile solvent mol­ecules. The cation (point group Unlabelled Image) has a bi­tetra­hedral {Hg2Se6} core with two bridging Se atoms and four terminal Se atoms.Unlabelled Image
