Gold(I) Complexes of Secondary Phosphines

Gold(I) complexes with secondary phosphines R2PH (1a-d) of the type R2PH*AuCl (2a-d) have been obtained in good yield from reactions of (carbonyl)chlorogold(I) and the corresponding ligad in diethylether.Both compounds 2a, b bearing aromatic substituents with R = 2,4,6-trimethylphenyl (mesityl) and 2-methylphenyl (o-tolyl), and compounds 2c, d with the bulky alkyl substituents R = t-butyl and R = cyclohexyl, resp., are air-stable crystalline solids. - The coordination compounds have been characterized by NMR and IR data, and - in the cases of 2b and 2c - by single crystal X-ray diffraction studies.Crystals of these two compounds are both monoclinic, space group P21/c with four formula units (Z = 4).The analysis shows independent monomers for compound 2c with no intermolecular Au...Au contacts.Molecules of 2b are arranged in centrosymmetrical dimers (head to tail) with an Au...Au distance of 3.56 Angstroem and a dihedral angle P-Au-Au'-P' of 180 deg. (This structural study is as yet incomplete and suffers from an unsatisfactory data set for 2b.) It appears that intermolecular contacts are largely controlled by steric effects. - Key words: Gold(I) Complexes, Secondary Phosphines, NMR Spectra, X-Ray
