A new complex,[Ni(acac)_2(NITQ)_2]·2CH_2Cl_2 1(acac=acetylacetone,NITQ=2-(2’-quinoxalinyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide),was synthesized and characterized by elemental analysis,IR spectroscopy,UV-Vis absorption spectrum,and single-crystal X-ray diffraction.The crystal belongs to the monoclinic system,space group P2_1/c with a=9.6970(19),b=20.410(4),c=12.166(2)A,β=93.89(3)°,M_r=997.43,V=2402.3(8)A~3,Z=2,D_c=1.379 g/cm~3,F(000)=1040,μ=0.684 mm~(-1),the final R=0.0423 and wR=0.1197 for 2884observed reflections(I>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,Cl…O weak contact andπ…πstacking interactions.Moreover,the luminescent properties of the ligand and compound 1 were further investigated in detail.
A new complex, [Ni (acac) _2 (NITQ) _2] · 2CH_2Cl_2 1 (acac = acetylacetone, NITQ = 2- (2’-quinoxalinyl) -4,4,5,5-tetramethylimidazoline-1-oxyl- oxide was synthesized and characterized by elemental analysis, IR spectroscopy, UV-Vis absorption spectrum, and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P2_1 / c with a = 9.6970 B = 20.410 (4), c = 12.166 (2) A, β = 93.89 (3) °, M_r = 997.43, V = 2402.3 (8) A~3, Z = 2, D_c = 1.379 g / cm~3, F (000) = 1040, μ = 0.684 mm -1, the final R = 0.0423 and wR = 0.1197 for 2884observed reflections (I> 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, Cl ... O weak contact and π ... πstacking interactions. More than the luminescent properties of the ligand and compound 1 were further investigated in detail.
