Treatment of > (M = Cr a, Mo b or W c) with 1 equivalent of or ClO4 (tht = tetrahydrothiophene) afforded the neutral binuclear complexes > (X = Cl 1a-1c or C6F5 2a-2c), or the cationic derivatives >ClO4 3a-3c.Complexes 2 and 3 are readily deprotonated by (acac = acetylacetonate) to give the tris(diphenylphosphino)methanide species > 4a-4c and > (5a-5c).Trinuclear compounds of the type <>2Au> 6a-6c were obtained by reaction of > with in the ratio 2:1.Single-crystal structure determinations were performed for compounds 1b, 2b and 4b.In the neutral complexes 1b and 2b the atoms C(2) (carbonyl), Mo, P(1) (co-ordinated to Au) and Au are essentially coplanar; the principal structural differences between the neutral and anionic (4b) complexes are the shorter P-C bonds and a rotation about the C-P(1) bond in the latter complex.
