The Cu atom in the title compound, [Cu2(C4H4O4)(NO3)2(C12H8N2)2(H2O)2], adopts an octahedral geometry that is distorted tetragonally, as seen in the copper–water [Cu—O 2.657 (4) Å] and copper–nitrate [Cu—O 2.525 (4) Å] bonds. The water molecule bridges adjacent molecules into a linear chain, and neighboring chains are linked by hydrogen bonds into a layer structure.

A solution of copper nitrate hexahydrate (0.24 g, 1 mmol) in water (5 ml) was
added to a mxiture of 1,10-phenanthroline (0.18 g, 1 mmol) and succinic acid
(0.12 g, 0.5 mmol) in a methanol–water mixture (50:5O, 10 ml) to give an
immediate blue solution. Blue crystals deposited from this solution after it
was set aside for a week. Calculated for C28H24Cu2N6O12: C 44.01, H
3.67, N 11.01%; found: C 43.71, H 3.95, N 10.87%.

Copper succinate is a Lewis acid that is capable of forming complexes with nitrogen-donor ligands. For example, it has been characterized as the bis[N-(2-hydroxyethyl)ethylenediamine)] (Pajunen & Pajunen, 1978) and diethyleletriamine (Pajunen et al., 1966) adducts, and as a decahydrated 1,10-phenanthroline adduct that cocrystallizes with copper dihydroxide (Zheng et al., 2000).
Molecules of µ-succinato-bis[aquanitrato(1,10-phenanthroline)copper(II)], (I), are packed such that the water-coordinated Cu atom [Cu—Owater = 1.984 (3) Å] at either end of the centrosymmetric molecule is water-bridged to adjacent Cu atoms [Cu—Owater = 2.657 (4) Å] to furnish a jagged chain that runs along the b axis. The donor water molecule uses one of its H atoms to form an intramolecular hydrogen bond to the double-bond carbonyl O atom [O···O = 2.551 (4) Å]. The other is used to bind to the copper-bonded O atom [Cu—O = 2.525 (4) Å] of the nitrate group [O···Oi = 2.739 (5) Å; symmetry code: (i) 2 - x, -y, 1 - z] to link neighboring chains into a layer structure (Fig. 1). The geometry of the Cu atom is an octahedron that is tetragonally distorted as seen in the rather long copper–water and copper–nitrate bonds.
