摘要 以2-吡啶甲醛,对氨基吡啶,Cu Cl2·2H2O和Na N3为原料,经配位反应合成了一个新型的二维配合物[Cu4(N3)6(mpm)2]n[1,mpm为(甲氧基)(2-吡啶基)甲醇],其结构经IR,元素分析,X-射线单晶衍射和X-射线粉末衍射表征。1(CCDC:1 405 719)属单斜晶系,空间群P21/n,晶胞参数a=14.290 5(15),b=11.286 3(10),c=15.808 5(14),F(000)=1 552,Dc=2.095 g·cm-3,V=2 481.2(4)3,Mr=782.67,Z=4,μ=3.452mm-1,R1=0.048 5,ωR2=0.096 8。1的最小不对称单元由四个Cu(Ⅱ)构成,不对称单元之间通过两个N-3分别以EO和EE模式桥连。 A novel copper-azido complex, [ Cu, ( N3 ) 6 (mpm) 2]n In [ 1, mpm = (methoxy) ( pyridine-2- yl) methanol], was synthesized by coordination reaction, using 2-pyridinecarboxaldehyde, 4-aminopyridine, CuC12 · 2H2O and NaN3 as materials. The structure was characterized by IR, elemental analysis, single-crystal X-ray and powder X-ray diffraction. 1( CCDC: 1 405 719) belongs to mono- clinic and space group P21/n. The cell parameters of 1 was a = 14.290 5 ( 15 ) A, b = 11. 286 3 (10) A,c=15.8085(14) A, F(000) =1 552, Dc=2.095 g. cm-3, V=2481.2(4) A3, Mr= 782.67, Z = 4,/.t = 3. 452 mm^-1, R1 = 0.048 5, toR2 = 0.096 8. The minimum unit of 1 was constituted by four Cu( 11 ). Different units was connected by two azides ions with EO and EE bridging modes, respectively.
