摘　　要：A novel nickel complex[Ni_(2)L_(2)Phen_(3)]·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 P1.Crystal data for the title complex:C58H44N8Ni2O9,Mr=1108.35,a=11.8648(4),b=12.7369(4),c=17.0728(5)A,α=97.694(3),β=96.702(2),γ=99.566(3)°,V=2495.66(14)A^(3),Z=2,T=293(2) K,Dc=1.475 g/cm^(3),μ(Mo Kα)=0.824 mm^(–1),F(000)=1140,R=0.0757,w R=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 e V.
