The asymmetric unit of the title compound, [CuCl(2)(C(5)H(6)N(2))(4)]·H(2)O, contains two crystallographically independent complex mol-ecules and two water mol-ecules. The Cu(II) ion in each mol-ecule is six-coordinated in an elongated octa-hedral geometry, with the equatorial plane defined by four pyridine N atoms of four amino-pyridine ligands and the axial positions occupied by two Cl atoms. In the crystal structure, mol-ecules are linked into a three-dimensional framework by C-H⋯Cl, O-H⋯Cl, N-H⋯O, N-H⋯Cl and N-H⋯N hydrogen bonds and C/N-H⋯π inter-actions involving the pyridine rings.
标题化合物[CuCl₂(C₅H₆N₂)₄]·H₂O的不对称单元包含两个晶体学独立的络合分子和两个水分子。每个分子中的Cu(II)离子以拉长的八面体几何构型进行六配位,赤道平面由四个氨基吡啶配体的四个吡啶N原子定义,轴向位置由两个Cl原子占据。在晶体结构中,分子通过C-H⋯Cl、O-H⋯Cl、N-H⋯O、N-H⋯Cl和N-H⋯N氢键以及涉及吡啶环的C/N-H⋯π相互作用连接成三维框架。
