catena‐Poly[[bis(1‐vinyl‐1H‐imidazole‐κN3)copper(II)]‐μ‐phthalato‐κ2O:O′]

The title compound, [Cu(C8H4O4)(C5H6N2)2]n, exhibits a polymeric zigzag chain structure extended along the c axis in the solid state. Each CuII ion is located on a crystallographic center of symmetry and is coordinated by two N [Cu—N = 1.993 (3) A] and two O [Cu—O = 1.952 (2) A] atoms in a distorted square-planar geometry. Weak C—H⋯O inter­actions contribute to the crystal packing stability.
