合成并研究了二硫代草酰胺配体(茜草酸)的两种非晶态配合物：Cu(C2S2N2H2)(H20)和Ni4(C2S2N2H3)2(C2S2N2H2)3(H20)o，25。这两种化合物基本上具有相同的局部结构。所提出的结构模型可以用以下特征来描述：(I)配体是反式构象平面；(Ii)配位是由四个配位原子(S，N)保证的，镍环境是正方形平面；(Iii)这样形成的带垂直于配体平面堆叠，间隔等于3.6A。
Two amorphous complexes of the dithiooxamide ligand (rubeanic acid) have been prepared and studied: Cu (C2S2N2H2)(H20) and Ni4 (C2S2N2H3) 2 (C2S2N2H2) 3 (H20) o, 25. Both compounds have essentially the same local structure. The proposed structural model can bedescribed by the following features:(i) the ligand is in a trans conformation and planar;(ii) the coordination is ensured by the four donoratoms (S, N), and the Ni environment is square planar;(iii) the ribbons thus formed stack perpendicularly to the ligand plane with an interval equal to 3.6 A.
