Analysis of the main structural trends for biscyclometalated dinuclear rhodium compounds with nitrogen donor axial ligands

摘要

A new series of biscyclometalated dinuclear rhodium(II) compounds with the general formula Rh2(O2CR)2(PC)2 (N)2 have been obtained, where PC is a cyclometalated phosphine, R an aliphatic group, and N a nitrogen donor ligand. The crystal structures for these compounds have been determined by X-ray diffraction. The most important structural trends have been analyzed, and have also been compared with the same parameters for different analogous compounds described previously in the literature.
