Beyond Heterobimetallic Complexes: Synthesis, Characterization, and Applications

Considering the remarkable luminescence properties and biological activities of heterobimetalliccompounds, they have gained ascending and comprehensive interest in the realm of catalysisresearch. Additionally, the preparation of heterobimetallic complexes could be challenging andrequire a rational synthetic approach concerning the compatibility and stability of the ligands andmetals. A stepwise synthetic pathway could yet be another alternative method for the preparation ofheterobimetallic complexes. In this approach, a metal complex is prepared, and a ditopic bridgingligand (a donor ligand possessing two binding sites for the coordination of metal atoms) is bound tothe first metal, which is followed by the coordination of the second metal complex. Among theselinker ligands, ۱,۱-bis(diphenylphosphino)methane (dppm) is a suitable candidate for thecoordination of various metals to form homo- and heterobimetallic complexes. We have synthesizedand characterized some new heterobimetallic complexes (Figure ۱), which contain two differentmetals such as platinum group metals (PGMs), Au, and Ag. These heterobimetallic compounds areconstructed by using a dppm ligand. The biological, optical, and catalytic properties of thesecomplexes are investigate
