ZnTPP axially coordinated with a novel dipyridylamine ligand : Hydrothermal synthesis and crystal structure
A novel complex ZnTPPL(1)center dot 3DMF 1 (TPP = tetraphenylporphyrin, L(1) = N-(4-(9-carbazolyl) phenyl)-N,N-di(4-pyridyl)amine) was prepared by a hydrothermal method and characterized by elemental analysis, IR, and single-crystal X-ray diffraction analysis. Compound 1 crystallizes in triclinic, s...

| Summary: | A novel complex ZnTPPL(1)center dot 3DMF 1 (TPP = tetraphenylporphyrin, L(1) = N-(4-(9-carbazolyl) phenyl)-N,N-di(4-pyridyl)amine) was prepared by a hydrothermal method and characterized by elemental analysis, IR, and single-crystal X-ray diffraction analysis. Compound 1 crystallizes in triclinic, space group P (1) over bar with a = 13.3082(2), b = 14.3276(2), c = 18.6120(3) angstrom, alpha = 109.853(1), beta = 95.054(1), gamma = 98.832(1)degrees, V = 3260.57(9) angstrom(3), Z = 2, D(c) = 1.334 g/cm(3), C(81)H(69)N(11)O(3)Zn, M(r) = 1309.84, mu(MoK alpha) = 0.438 mm(-1), F(000) = 1372, GOF = 1.159, the final R = 0.0482 and wR = 0.1479 for 12091 observed reflections (I > 2 sigma(I)). Crystal structure analyses revealed that L(1) utilizes one pyridyl N atom to bind Zn via axial coordination, affording a 1:1 complex. The binding constant was estimated to be 1.74(7) x 10(4) M(-1) from electronic spectra measurements. |
