A series of cofacial bisorganometallic diporphyrin complexes, M 2 III/III R 2 DPB (M=Ru, Os; R=methyl, p-tolyl, 3,5-bis(trifluoromethyl)phenyl; DPB=diporphyrinatobiphenylene), has been synthesized by addition of the corresponding Grignard reagents to the dication of the dimetallodiporphyrins. These paramagnetic compounds have been characterized by 1 H NMR, cyclic voltammetry, UV-vis, and mass spectrometry

An unusually stable, bridged dinitrogen complex of a biphenylene bridged diporphyrin is described. The complex (μ-N 2 )Ru 2 DPB(1-tert-butyl-5-phenylimidazole) 2 (DPB=diporphyrinatobiphenylene tetraanion) is proposed as a model for a dinitrogen reduction catalyst based on cofacial metallodiporphyrins. The differences in binding by bridged and nonbridged ligands to the two coordination sites between
