Hydrothermal Preparation And Photophysical Properties Of A Ni(Ii) Complex Containing Quinoline Derivative And Phen Ligands

A novel nickel complex [Ni(2)L(2)Phen(3)] center dot 3H(2)O (HL = 3-hydroxy-2-methylquioline-4-carboxylic acid) has been synthesized by a hydrothermal approach and is structurally determined by single-crystal X-ray diffraction. The title complex crystallizes in triclinic space group P (1) over bar. Crystal data for the title complex: C58H44N8Ni2O9, M-r = 1108.35, a = 11.8648(4), b = 12.7369(4), c = 17.0728(5) angstrom, alpha = 97.694(3), beta = 96.702(2), gamma = 99.566(3)degrees, V = 2495.66(14) angstrom(3), Z = 2, T = 293(2) K, D-c = 1.475 g/cm(3), mu(MoK alpha) = 0.824 mm(-1), F(000) = 1140, R = 0.0757, wR = 0.2129 and GOF = 1.017. The nickel ions are surrounded by five oxygen and six nitrogen atoms to yield two slightly distorted octahedral geometries. Solid-state photoluminescence spectrum reveals that it shows blue purple emission. Solid-state UV/Vis diffuse reflectance spectroscopy exhibits that it has an optical band gap of 1.702 eV.
