Abstract

The reaction of the clusters [Pt32-CO)3L3] (L = PCy3, PPhCy2, PPhiPr2, and PiPr3) with mercury halides (Hg2X2 and HgX2) gave trigonal-bipyramidal pentametallic clusters of the type [{HgX}2{Pt32-CO)3L 3}] which were fully characterized by multinuclear NMR. While these clusters are monomeric in solution, the X-ray crystal structure of [{HgBr}2{Pt32-CO)3(PPhCy 2)3}] shows that this compound is dimeric in the solid state and consists of two Hg2Pt3 trigonal bipyramids, each being bonded to a bromine atom on one side and two bridging bromine atoms on the other side. Crystal data are as follows: trigonal space group R3c (No. 167), a = 21.232 (3) Å, c = 58.494 (9) Å, V = 22836 (3) Å3, and Z = 6. The structure was refined to R = 0.038 (Rw = 0.044) for 1294 data with I ≥ 3.0(I).
