In the crystal structure of the title compound, [CuCl(C(5)H(5)N)(4)][N(CN)(2)]·2C(6)H(5)N, the copper(II) cations are coordinated by one chloride anion and four N-bonded pyridine ligands into discrete complexes. The copper(II) cation shows a square-pyramidal coordination environment, with the chloride anion in the apical position. However, there is one additional chloride anion at 3.0065 (9) Å, leading to a disorted octa-hedral coordination mode for copper. The copper(II) cation, the chloride ligand and the central N atom of the dicyanamide anion are located on twofold rotation axes. Two pyridine solvent molecules are observed in general positions.
在标题化合物[CuCl(C₅H₅N)₄][N(CN)₂]·2C₆H₅N的晶体结构中,铜(II)阳离子由一个氯离子阴离子和四个与氮原子键合的吡啶配体配位形成离散的配合物。铜(II)阳离子呈现出四方锥配位环境,氯离子阴离子位于顶端位置。然而,在3.0065 (9) Å处还有一个额外的氯离子阴离子,导致铜呈现出扭曲的八面体配位模式。铜(II)阳离子、氯配体和双氰胺阴离子的中心氮原子位于二重旋转轴上。在一般位置观察到两个吡啶溶剂分子。
