Abstract

The synthesis and characterization of a new binucleating porphyrin ligand, a,a-5, 1 5-bis(o-(nicotinoylamido)phenyl)-2,8, 12,18- tetraethyl-3,7,13,17-tetramethylporphyrin, [H2(DPE)]-(pyh is reported. Treatment of [H 2(DPE)]-(pyh with methanol solutions of Ni(II) or Cu(II) leads to the formation of mononuclear metal complexes, [M(DPE)]-(pyh, 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)]-(pyhM'Cl2, can be accomplished using the reagent M'(DMSOhCI2, M' = Pd, Pt, and Zn. [Ni(DPE)]-(pyh and [Cu(DPE)]-(pyhPtCI2 have been characterized by single-crystal X-ray analysis. Crystal data for [Ni(DPE)]-(pyh: Ni02N 8- C56H52·2CHCI3, triclinic, PI, a= 14.306 (4) A, b = 14.719 (5) A, c = 14.296 (5) A, a= 94.86 (3) 0 , {J = 96.38 (3) 0 , -y = 63.45 (2) 0 , Z = 2, R = 0.049, and Rw = 0.064. Crystal data for [Cu(DPE)]-(pyhPtCI2: CuPt02N 8C 56H 52, triclinic, PI, a= 19.333 (1) A, b = 23.74 (I) A, c = 12.984 (5) A, a= 103.28 (4) 0 , fJ = 108.29 (3) 0 , -r = 76.47 (3) 0 , Z = 4, R = 0.073, and Rw = 0.085. Pt-Pt distances between the two molecules in the asymmetric unit are 3.766 (3) A.
