Abstract
Reaction of NaH with [Au(C6F5)2(Ph2PCH2PPh2)]ClO4 causes both deprotonation of the methylene group and elimination of the anion and leads to the neutral bis(diphenylphosphino)methanide complex [Au(C6F5)2(Ph2PCHPPh2)], which further reacts with gold(I) or silver(I) derivatives to give bi- or tri-nuclear complexes. The structures of a binuclear and a trinuclear gold derivative have been confirmed by X-ray crystallography. Crystals of [(C6F5)2Au(Ph2P[graphic omitted]u(C6F5)] are monoclinic, space group P21/m, with a= 10.003(2), b= 17.389(4), c= 11.754(3)Å, β= 103.53(2)°, and Z= 2; R= 0.034 for 4 016 reflections. Crystals of [(C6F5)2Au(Ph2P[graphic omitted]HPPh2)Au(C6F5)2]ClO4(CHCl3 solvate) are monoclinic, space group P21/m, with a= 17.456(6), b= 17.704(6), c= 17.749(8)Å, β= 92.86(5)°, and Z= 2; R= 0.096 for 5 230 reflections.Keywords
