A triangulo-triplatinum cluster with no bridging atom: the structure of [Pt3(2,6-Me2C6H3NC)2(µ-Ph2PCH2PPh2)3]2+
Abstract
The complex cation [Pt3(2,6-Me2C6H3NC)2(µ-dppm)3]2+, dppm = Ph2PCH2PPh2, characterized by X-ray structure analysis, is the first triplatinum cluster which contains no single-atom bridging ligand; it completes a series of clusters based on the equatorial [Pt3(µ-dppm)3] unit in which two axial ligands, L, are present and in which structures with Pt3(µ3-L)2, Pt3(µ3-L)(L) and Pt3(L)2 units are very close in energy.
