摘要
通过水热合成的方法,以1,4-环己烷二羧酸、2,4-二氨基-6-甲基三嗪和CdCl_2·2.5H_2O为原料合成了一种单核的化合物{Cd(dmt)_2(Hchdc)_2(H_2O)_2}_n(dmt=2,4-diamino-6-methyl-triazine,H2chdc=1,4-cyclohexanedicarboxylic acid),并进行了IR和X射线单晶衍射(常温)的分析.结果表明,该化合物属于P2/c空间群,单斜晶系,晶胞参数:a=1.330 26(11)nm,b=0.541 47(4)nm,c=2.415 54(16)nm,β=115.751(3)°,V=1.567 1(2)nm^3,Z=2,Dc=1.570g/cm^3,F(000)=764,R1=0.035 2,wR2=0.092 7.该化合物中,中心金属离子Cd(II)与氧相连形成六配位构型,并通过4种不同的氢键作用最终形成了三维的堆积结构.
A compound {Cd（dmt）_2（Hchdc）_2（H_2O）_2}nwas synthesized under hydrothermal method by using 1,4-cyclohexanedicarboxylic acid,2,4-diamino-6-methyl-triazine as well as CdCl_2·2.5H_2O and characterized by IR and X-ray single-crystal diffraction analysis.The results show the title compound belongs to monoclinic system space group P2/c,with crystal cell parameters being a = 1.330 26（11）nm,b = 0.541 47（4）nm,c = 2.415 54（16）nm,β= 115.751（3）°,V =1.567 1（2）nm^3,Z =2,Dc=1.570g/cm^3,F（000）=764.In the compound,a center metal ion Cd（Ⅱ）is six coordinated by oxygen atoms and a three-dimensional stacked structure eventually formed with four different hydrogen-bonding interactions.
