The crystal structure of the polymeric title compound, {[HgCl(2)(C(18)H(18)N(4))]·C(3)H(7)NO}(n), features an N-heterocyclic ligand which links adjacent HgCl(2) units into a helical chain running along the b axis. The coordination geometry of the Hg(II) atom is a distorted tetra-hedron. The dimethyl-formamide mol-ecule is disordered over two positions in a 1:1 ratio, and is linked to the complex mol-ecules via N-H⋯O hydrogen bonds.
聚合标题化合物{[HgCl₂(C₁₈H₁₈N₄)]·C₃H₇NO}ₙ的晶体结构具有一个N-杂环配体,该配体将相邻的HgCl₂单元连接成沿b轴延伸的螺旋链。Hg(II)原子的配位几何形状为扭曲的四面体。二甲基甲酰胺分子在两个位置上以1:1的比例无序排列,并通过N-H⋯O氢键与配合物分子相连。
