摘要：

Using a cofacial biphenylene-bridged bis(porphyrin) (DPB, l,8-bis[5-(2,8,13,17-tetraethyl-3,7,12,18-tetramethyl) porphyrin]biphenylene), a general synthetic method for the preparation of heterodinuclear complexes with 3d, 4d, and 5d transition metals is described. For (OSII)(RunII)DPB, and DPB ligand provides a high local concentration of the mixed-metal pair, thereby controlling the stoichiometry of the metal-metal interaction and facilitating the formation of an intramolecular, paramagnetic, osmium-ruthenium double bond. The magnetic and spectroscopic properties are found to be similar to those of the analogous homodinuclear ruthenium and osmium DPB compounds. © 1990, American Chemical Society. All rights reserved.
