The borole-containing carbonylmetalates [(η-C4H4BPh)Re(CO)3]â ([Re]â) and [(η-C4H4BPh)Fe(CO)2H]â ([Fe]â) were used for the synthesis of heterometallic complexes with ReâHg, ReâCu, ReâAg, ReâAu or FeâPt metalâmetal bonds, respectively. The complex [Re]âHgâ[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]âHgâCl 2 which was independently prepared from [Re]â and an excess of HgCl2. The reaction of [Fe]â 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 FeâPt bonds.
