摘要 以2,4-二氨基-6-(2'-吡嗪)-均三嗪(PZTA)为配体,与CuCl2[n(PZTA)∶n(CuCl2)=1∶1]反应合成了一种新的铜配合物{[Cu(PZTA)2Cl]Cl(1)},其结构经IR,元素分析和X-射线单晶衍射表征。1属单斜晶系,空间群C2/c,晶胞参数a=11.600(2),b=12.700(3),c=14.600(3),β=102.80(3)°,V=2 097.423,Z=4,Dc=1.624 g·cm-3,μ=1.331 mm-1,F(000)=1 036.0,S=1.106,Rint=0.036,R1=0.034 2,wR2=0.088 6。1由一个Cu(Ⅱ),两个PZTA,一个配位Cl和一个游离Cl-构成。1通过弱相互作用和氢键作用堆积成二维层状结构和三维堆积结构。1的初始分解温度为300℃。 A novel copper complex { [ Cu (PZTA) 2 Cl ] C1 ( 1 ) } was synthesized by reaction of CuCl2 and 2,4-diamino-6-(2′-pyrazino)-triazine(PZTA) with the molar ratio of 1 : 1. The structure was characterized by IR, elemental analysis and X-ray single crystal diffraction. 1 belongs to monoclinic, space group C2/c with a = 11. 600 (2) A, b = 12.700 (3) A, c = 14. 600 (3) A,β = 102.80 (3) °, V=2097.42A3, Z=4, Dc=1.624g.cm-3 /x=1 331mm-1 F(000) =1036.0, S=1.106 Rint =0.036, R1 =0.034 2, wR2 =0.088 6. 1 consists of one Cu( Ⅱ ), two PZTA ligands, a chlofine ligand and a free chlorine ion. Two-dimensional and three-dimensional structures were formed by the weak interaction and hydrogen bonding. The initial decomposition temperature of 1 was 300 ℃.
