Mixed Rh–Pt carbonyl clusters: synthesis and X-ray crystallographic characterisation of [Rh5Pt(CO)15]–[(Ph3P)2N]+
Abstract
The [Rh5Pt(CO)11(µ3-CO)4]– anion, which has been prepared by two independent routes, is shown to be structurally related to [Rh6(CO)12(µ3-CO)4][one Rh(CO)2 group is replaced by a Pt(CO) group] both in the solid state (X-ray) and in solution (n.m.r.); evidence is also presented for a further reduced mixed anion [Rh2Pt-(CO)x]n–.
