摘要
合成了草酰胺氮杂大环Schiff碱配合物[CuL]·CH3OH(H2L=2,3 二氧 5,6,14,15 二苯并 1,4,8,12 四氮杂环十五 7,12 二烯),通过元素分析、红外光谱和X射线晶体衍射对其结构进行了表征.[CuL]·CH3OH晶体为单斜晶系,P2(1)/n空间群,晶胞参数a=0.9221(3)nm,b=1.6149(5)nm,c=1.2269(4)nm,β=92.165(6)°;Z=4,F(000)=884,R1=0.0413,wR2=0.0840.二价铜离子位于大环的空穴中,以近平面正方形模式与氮杂大环上的四个氮原子配位.
An oxamido azacyclic Schiff base complex ·CH_3OH (H_2L = 2, 3 - dioxo - 5, 6, 14, 15 - dibenzo - 1, 4, 8, 12 - tetraazacyclopentadeca - 7, 12 - diene) was synthesized and characterized by elemental analysis, IR and X-ray crystalline diffraction. Crystals of the complex ·CH_3OH are monoclinic, space group P2(1)/n, with a =0.922 1(3) nm, b = 1.614 9(5) nm, c = 1.226 9(4) nm,β = 92.165(6)°; Z = 4, F(000) = 884, R_1 = 0.041 3, wR_2 = 0.084 0. The Cu(II) cation lies in the macrocyclic cavity coordinated in a slightly distorted square-planar manner by four N atoms of the aza-macrocycle.
