Abstract: In the title compound, {[Cu(C₈H₄O₄)(C₁₄H₈N₄)(H₂O)]·C₃H₇NO·H₂O}_n, the Cu^II atom binds a water molecule and is chelated by the pyrazinophenanthroline N-heterocycle. It is also linked covalently to an isophthalate dianion that lies on a special position of site symmetry 2. The dianion serves as a spacer that connects adjacent square-pyramidal metal atoms into a zigzag chain propagating along the c axis of the orthorhombic unit cell. The chain motif is consolidated into a layer structure by hydrogen bonds involving both the coordinated and uncoordinated water molecules. The copper atom and the coordinated water molecule lie on a mirror plane, while the N-heterocycle, the disordered uncoordinated water molecule and the disordered dimethylformamide solvent molecule lie across a mirror plane.
