In the crystal structure of the title complex, Cu(2)(C(10)H(20)N(4)O(2))(C(10)H(8)N(2))(2)(2), the deprotonated dmaeoxd(2-) ligand {H(2)dmaeoxd is N,N'-bis[2-(dimethylamino)ethyl]oxamide} occupies an inversion centre at the mid-point of the central C-C bond and is thus in a trans conformation. The two Cu(II) atoms are located in slightly distorted square-based pyramidal environments. The binuclear units interact with each other via pi-pi interactions to form a one-dimensional chain extending in the c direction.
在标题配合物Cu₂(C₁₀H₂₀N₄O₂)(C₁₀H₈N₂)₂₂的晶体结构中,去质子化的dmaeoxd²⁻配体{H₂dmaeoxd为N,N'-双[2-(二甲氨基)乙基]草酰胺}位于中心C-C键中点的对称中心上,因此呈反式构象。两个Cu(II)原子位于略微扭曲的四方锥环境中。双核单元通过π-π相互作用相互作用,形成沿c方向延伸的一维链。
