在甲醇溶液中合成了一系列IIB过渡金属Zn(II), Cd(II)的二羟乙基二硫代氨基甲酸[(EtOH)2dtc]的配合物, 并对配合物M[(EtOH)2dtc]2L [M＝Zn (1), Cd (2), L＝2,2'-联吡啶; M＝Zn (3), Cd (4), L＝邻菲啰啉]进行了红外光谱、元素分析、热重分析表征工作. 热重分析表明配合物1～4中DTC配体比中性配体更易失去, 热分解最终产物为相应的氧化物. 对化合物1, 2做了X-ray单晶衍射分析, 1为单斜晶系, P21/c空间群, 晶胞参数a＝0.72146(5) nm, b＝2.61720(18) nm, c＝1.59438(11) nm,?b＝97.899(2)°, V＝2.9820(4) nm3, Z＝4, m＝1.133 mm－1, Dc＝1.297 Mg•m－3; 2为三斜晶系, P-1空间群, 晶胞参数a＝1.0075(2) nm, b＝1.1580(2) nm, c＝1.1777(2) nm, a＝70.92(3)°, b＝85.71(3)°, γ＝81.02(3)°, V＝1.2822(4) nm3, Z＝2, m＝2.118 mm－1, Dc＝1.630 Mg•m－3.

A series of IIB group metal Zn(II), Cd(II) complexes with dithiocarbamate (dtc) ligand (HOCH2CH2)2dtc have been synthesized in methanol solution. All the complexes M[(HOCH2CH2)2dtc]2L [M＝Zn (1), Cd (2); L＝2,2'-bipyridyl; M＝Zn (3), Cd (4), L＝1,10-phenanthroline] were characterized by IR spectra, elemental analysis and TGA. The TGA results show that all the final thermolysis residues of the above complexes are their respective metal oxides. Compounds 1 and 2 were also determined by single crystal X-ray diffraction analysis. The complex 1 crystallizes in a monoclinic system with space group P21/c and parameters a＝0.72146(5) nm, b＝2.61720(18) nm, c＝1.59438(11) nm, b＝97.899(2)°, V＝2.9820(4) nm3, Z＝4, m＝1.133 mm－1, Dc＝1.297 Mg•m－3. The complex 2 crystallizes in a triclinic system with space group P-1, and parameters a＝1.0075(2) nm, b＝1.1580(2) nm, c＝1.1777(2) nm, a＝70.92(3)°, b＝85.71(3)°, γ＝81.02(3)°, V＝1.2822(4) nm3, Z＝2, m＝2.118 mm－1, Dc＝1.630 Mg•m－3.
