Dimethylsulfide reacts with (triphenylphosphine) gold(I) trifluoromethanesulfonate to give quantitative yields of the mixed ligand complex [(Ph3P)Au(SMe2)]+O3SCF3- (1). The structure of compound 1 has been determined by an X-ray crystal structure analysis. The lattice contains independent anions and (monomeric) cations, which have a linear P-Au-S axis. Attempts to produce a binuclear. dicationic complex through addition of a second equivalent of [(Ph3P)Au]+ failed and lead to decomposition products including [(Ph3P)2Au]+O3SCF3-.

Use of mixed-ligand (bromide and thiocyanate ions) coordination with nickel has led to the crystallization of the title compound, (C24H20As)2[Ni(NCS)2Br2]. X-ray crystal structure analysis reveals that the asymmetric unit contains one (C6H5)4As+ cation and one half [Ni(NCS)2Br2]2− anion, the latter lying on a crystallographic twofold axis.

Racemates of (η3-allyl)tricarbonyliron lactone complex Fe(CO)3{η1:η3-C(O)XCH2CHCMeCH2} 1a (X = O) and (η3-allyl)tricarbonyliron lactam complex 2a (X = NMe) are resolved on a preparative scale by HPLC on cellulose tris(3,5-dimethylphenyl)carbamate/silica gel RP-8 and the absolute configuration of (-)-2a is determined by X-ray crystal structure analysis.
