摘要
In the title compound, [Cu(C8H4O4)(C14H8N4)(H2O)](.)-C3H7NO (H2O)-H-., the Cu-II atom binds a water molecule and is chelated by the pyrazinophenanthroline N-heterocycle. It is also linked covalently to a terephthalate dianion that lies on a special position of 1 site symmetry. This dianion serves as a spacer to connect adjacent square-pyramidal metal atoms into a helical chain that propagates along the b axis of the monoclinic unit cell. The chain motif is consolidated into a layer structure by hydrogen bonds involving the coordinated and uncoordinated water molecules. The Cu atom and the coordinated water molecule lie on a mirror plane, while the N-heterocycle, the disordered uncoordinated water molecule and disordered dimethylformamide solvent molecule lie about a mirror plane.
