The asymmetric unit of the title compound, [CuCl(C(12)H(12)N(2)O)]CuCl(C(12)H(12)N(2)O)(H(2)O)(2), contains two different discrete cations. In one cation, the Cu(II) ion is coordinated in a slightly distorted square-planar geometry, while in the other the Cu(II) ion is in a slightly distorted square-pyramidal environment. In the crystal structure, there are O-H⋯O hydrogen bonds between coordinated water mol-ecules and perchlorate anions. Both types of cations are linked into one-dimensional chains along the b axis by weak electrostatic Cu⋯Cl inter-actions, with Cu⋯Cl distances of 2.8088 (16) and 3.2074 (17) Å.
标题化合物[CuCl(C₁₂H₁₂N₂O)]CuCl(C₁₂H₁₂N₂O)(H₂O)₂的不对称单元包含两种不同的离散阳离子。在一种阳离子中,Cu(II)离子以略微扭曲的平面正方形几何构型配位,而在另一种阳离子中,Cu(II)离子处于略微扭曲的四方锥环境中。在晶体结构中,配位水分子与高氯酸根阴离子之间存在O—H⋯O氢键。两种类型的阳离子通过弱静电Cu⋯Cl相互作用沿b轴连接成一维链,Cu⋯Cl距离分别为2.8088 (16) Å和3.2074 (17) Å。
