In the title complex, [Cu(C(7)H(4)NO(4))(C(5)H(5)N(2)O(2))(H(2)O)(2)], the Cu(II) ion is coordinated in a slightly distorted square-pyramidal enviroment. The basal plane is formed by an N atom and an O atom from a 5-methyl-1H-pyrazole-3-carboxyl-ate ligand and by two O atoms from two water ligands. The apical position is occupied by a carboxylate O atom from a 4-nitro-benzoate ligand. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link complex moleclues, forming extended chains parallel to the a axis.
在标题配合物[Cu(C₇H₄NO₄)(C₅H₅N₂O₂)(H₂O)₂]中，Cu(II)离子在一个轻微扭曲的四方锥环境中配位。基面由来自5-甲基-1H-吡唑-3-羧酸酯配体的一个N原子和一个O原子以及来自两个水分子配体的两个O原子构成。顶端位置由来自4-硝基苯甲酸酯配体的一个羧酸根O原子占据。在晶体结构中，分子间的O-H⋯O和N-H⋯O氢键连接配合物分子，形成平行于a轴的延伸链。
