THEORETICAL STUDY OF COMPLEXES OF THE TYPE [Pt3(M-L)3(L')3J-X (L=CO,SO2,CNH; L'=PH3,CNH; X=Tl+, Hg0, MPH3+ (M = Cu, Au, Ag))
The interaction between the [(μ-L)3(L')3] cluster (L = CO, SO2, CNH; L = PH3, CNH) and a series of fragments X (Tl+, Hg(0), AuPH3+, CuPH3+ and AgPH3+) was studied using ab initio methodology. The calculations suggest that the complexes formed are stable. We have studied these complexes...
