Chloro­methyl(η⁴-norborna­diene)­platinum(II), an unsymmetrical substituted precursor for Pt^II complexes

The title compound, [PtCl(CH₃)(C₇H₈)] or [(nbd)PtClMe] (nbd is norborna­diene), was formed in a partial substitution reaction of di­chloro(η⁴-norborna­diene)­platinum(II). The Pt atom exhibits tetrahedral coordination, involving the two η²–π bonds to the norborna­diene, one chlorine and one methyl substituent. Probably as a result of the symmetry of the norborna­diene and the approximately equal size of the methyl and chlorine substituents, these two substituents are disordered and have been refined, each with half-occupancy.
