摘要
A new complex, [Ni（acac）2（NITQ）2]-2CH2C12 1 （acac = acetylacetone, NITQ = 2-（2＂-quinoxalinyl）-4,4,5,5-tetramethylimidazoline-l-oxyl-3-oxide）, was synthesized and charac- terized by elemental analysis, IR spectroscopy, UV-Vis absorption spectrum, and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/c with a = 9.6970（19）, b = 20.410（4）, c = 12.166（2） A, β = 93.89（3）°, Mr = 997.43, V= 2402.3（8） A3, Z = 2, Dc = 1.379 g/cm3, F（000） = 1040,μ = 0.684 mm-1, the final R = 0.0423 and wR = 0.1197 for 2884 observed reflections （1 〉 2σ（I））. Compound 1 is found to assume a mononuclear structure, which is further linked into a three-dimensional （3D） supramolecular network by hydrogen-bonding, C1...O weak contact and π...π stacking interactions. Moreover, the luminescent properties of the ligand and compound 1 were further investigated in detail.
