The Cu(II) atom in the title complex, [Cu(C(14)H(11)O(3))Cl(C(10)H(8)N(2))], exists within a ClN(2)O(2) donor set defined by a chloride ion, an asymmetrically chelating carboxyl-ate ligand, and a symmetrically chelating 2,2'-bipyridine mol-ecule. The coordination geometry is square pyramidal with the axial site occupied by the O atom forming the weaker Cu-O inter-action. The hy-droxy group forms an intra-molecular hydrogen bond with the axial O atom, as well as an inter-molecular O-H⋯Cl hydrogen bond. The latter leads to the formation of [100] supra-molecular chains in the crystal, with the Cu(II) atoms lying in a line.
在标题配合物[Cu(C₁₄H₁₁O₃)Cl(C₁₀H₈N₂)]中,铜(II)原子存在于由氯离子、一个不对称螯合的羧酸根配体和一个对称螯合的2,2'-联吡啶分子所定义的ClN₂O₂供体集合中。配位几何形状为四方锥,轴向位置由形成较弱Cu - O相互作用的O原子占据。羟基与轴向O原子形成分子内氢键,以及分子间O - H⋯Cl氢键。后者导致在晶体中形成[100]超分子链,铜(II)原子排列成一条直线。
