Abstract

The borole-containing carbonylmetalates [(η-C4H4BPh)Re(CO)3]– ([Re]–) and [(η-C4H4BPh)Fe(CO)2H]– ([Fe]–) were used for the synthesis of heterometallic complexes with Re–Hg, Re–Cu, Re–Ag, Re–Au or Fe–Pt metal–metal bonds, respectively. The complex [Re]–Hg–[Re] 1 was characterized by X-ray diffraction and contains a linear metal chain. In the presence of HgCl2, redistribution reactions were observed, leading to [Re]–Hg–Cl 2 which was independently prepared from [Re]– and an excess of HgCl2. The reaction of [Fe]– with trans-[PtBr2(4-Mepy)2] (4-Mepy = 4-methylpyridine) afforded the trinuclear complex trans-[Pt[Fe]2(4-Mepy)2] 6 which was characterized by X-ray diffraction and contains two hydrido ligands which bridge the Fe–Pt bonds.
