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
