In the title complex, [Cu(C(7)H(5)O(3))(2)(C(21)H(18)N(4)O)(2)]·2H(2)O, the Cu(II) atom is located on a centre of inversion and exists in a tetra-gonally distorted octahedral geometry with a CuN(4)O(2) chromophore. The intra-molecular O-H⋯O hydrogen bond is highly strained due to the mol-ecular geometry and, as a result, is much shorter than expected. Inter-molecular C-H⋯O and C-H⋯O inter-actions are also observed.
在标题配合物[Cu(C₇H₅O₃)₂(C₂₁H₁₈N₄O)₂]·2H₂O中,Cu(II)原子位于对称中心,以CuN₄O₂发色团存在于四方畸变的八面体几何构型中。由于分子几何形状,分子内O—H⋯O氢键受到高度扭曲,因此比预期的要短得多。还观察到分子间的C—H⋯O和C—H⋯O相互作用。
