"Chloromethyl(η⁴-norbornadiene)platinum(II), an unsymmetrical substituted precursor for Pt^II complexes";
Acta Crystallographica Section E, 58 (2002), 387 - 388.

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.
