A series of binuclear rhodium(i) and iridium(i) complexes with 2,6-bis(benzimidazol-2-yl) pyridine (bzimpy) derivatives were synthesized and characterized by elemental analysis and spectroscopic methods. The molecular and crystal structures of complex 3d were determined by the single crystal X-ray diffraction technique. Their monometallic analogues were prepared to compare the catalytic properties of the bimetallic complexes. To determine the catalyst properties that result in a cooperative, bimetallic enhancement of the reaction rate, the systematic variation of the intermetallic distance and the ligand donor properties of the bimetallic complexes were explored based on the transfer hydrogenation reactions of ketones.
Evaluation of Cu(II) bzimpy complexes by 1H-NMR and catalytic activities

Copper(II) complexes (3a–d and 4a–d) containing tridentate 2,6-bis(benzimidazole-2-yl) pyridine (bzimpy) were synthesized and characterized by 1H-NMR, elemental analysis, IR, UV and mass spectroscopy. These complexes were tested as catalysts in transfer hydrogenation (TH). The effects of wingtip substituents on bzimpy ligand to the TH activity of Cu(II) complexes were investigated. Among the catalysts, complex 4d with sterically bulky bzimpy ligand showed the highest catalytic activity in this transformation.
