Synthesis and Crystal Structure of a Ni(Ⅱ) Complex of 2'-4-N,N'-(Dimethylaminobenzyl- idene)-3,5-dihydroxybenzoylhydrazide and Its Spectral Properties
cqvip:A new nickel(II) complex [NiL2](DMF)4 (HL = 2'-[4-N,N'-(dimethylamino- benzylidene)]-3,5-dihydroxybenzoylhydrazide) has been synthesized and its structure was charac- terized by IR,UV-Vis,1H NMR and elemental analysis. The fluorescence emission mechanism of the complex was discussed by fluorimetric spectra. The single-crystal structure was determined by X-ray diffraction analysis. The crystal belongs to the triclinic system,space group P1 with a = 0.9918(4),b = 1.1297(4),c = 1.1331(4) nm,α = 76.860(7),β = 75.105(6),γ = 89.022(7)°,V = 1.1936(8) nm3,Z = 1,μ = 0.472 mm-1,Dc = 1.319 g/cm3,F(000) = 502 and Rint = 0.0913. In the title compound,the nickel(II) atom is four-coordinated with two nitrogen atoms from amide and two oxygen atoms from keto group. The complex is centrosymmetric with nickel located at the center.
