Abstract

The reaction of Ru3(CO)12 with Pt(IPr)(SnBut3)(H) at 68 °C yielded the trigonal bipyramidal cluster Ru3Pt2(IPr)2(CO)12, 1, in 32% yield. The reaction of Os3(CO)12 with Pt(IPr)(SnBut3)(H) at 68 °C furnished the triosmium–monoplatinum cluster complex Os3Pt(IPr)(CO)12, 2, in 51% yield and the triosmium–diplatinum cluster complex Os3Pt2(IPr)2(CO)12, 3, in 19% yield. The reaction of Fe3(CO)12 with Pt(IPr)(SnBut3)(H) at room temperature resulted in cluster fragmentation to afford the diiron–monoplatinum cluster complex Fe2Pt(IPr)(CO)9, 4, in 44% yield. All four compounds were structurally characterized by single-crystal X-ray diffraction analyses.
