In the title compound, [Cu(C10H9N2O2)(C10H10N2O2)], the Cu(I) ion is situated at a crystallographic centre of inversion and is coordinated in a linear environment by two benzimidazole N atoms from two symmetry-related 2-propanoic-1H-benzimidazole ligands. The ligands are disordered in a sense that statistically one of the carb-oxy-lic acid groups in each mol-ecule is deprotonated. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into chains along the a-axis direction. These chains are additionally linked into infinite two-dimensional networks in the ab plane by N-H⋯O hydrogen bonds.
在标题化合物[Cu(C₁₀H₉N₂O₂)(C₁₀H₁₀N₂O₂)]中，Cu(I)离子位于一个晶体学对称中心，由来自两个对称相关的2-丙酸-1H-苯并咪唑配体的两个苯并咪唑N原子在直线型环境中配位。从统计学角度看，每个分子中的一个羧酸基团去质子化，因此配体是无序的。在晶体中，O—H⋯O氢键将分子沿a轴方向连接成链。这些链通过N—H⋯O氢键在ab平面上进一步连接成无限的二维网络。
