Stepwise addition of PtPPh3 fragments on [Re2(CO)10]. X-Ray crystal structures of the complexes [Re2Ptn(µ-CO)2n(CO)10 – 2n(PPh3)n](n= 2, 3), the first examples of tetra-and penta-nuclear rhenium–platinum mixed-metal clusters
Abstract
Up to three PtPPh3 fragments, originating from [Pt(PPh3)2(C2H4)], can be added to [Re2(CO)10] affording [Re2Ptn(µ-CO)2n(CO)10 – 2n(PPh3)n](n= 1, 2, 3) mixed metal clusters, with structures based on electron short (46 valence electrons) Re2Pt triangles condensed on the Re–Re hinge.
