The synthesis and characterization of a new binucleating porphyrin ligand, {alpha},{alpha}-5,15-bis(o-(nicotinoylamido)phenyl)-2,8,12,18-tetraethyl-3,7,13,17-tetramethylporphyrin, (H{sub 2}(DPE))-(py){sub 2} is reported. Treatment of (H{sub 2}(DPE))-(py){sub 2} with methanol solutions of Ni(II) or Cu(II) leads to the formation of mononuclear metal complexes, (M(DPE))-(py){sub 2}, in which the metal has inserted into the porphyrin core, leaving the pyridine binding site free. Addition of a second metal to form a binuclear complex, (M(DPE))-(py){sub 2}M{prime}Cl{sub 2}, can be accomplished using the reagent M{prime}(DMSO){sub 2}Cl{sub 2}, M{prime} = Pd, Pt, and Zn. (Ni(DPE))-(py){sub 2} and (Cu(DPE))-(py){sub 2}PtCl{sub 2} have been characterized by single-crystal X-ray analysis. Pt-Pt distances between the two molecules in the asymmetric unit are 3.766 (3) {angstrom}.
