Diaquabis(N,N-diethylnicotinamide-κN1)bis(4-formylbenzoato-κO1)zinc

In the title complex, [Zn(C 8 H 5 O 3 ) 2 (C 10 H 14 N 2 O) 2 (H 2 O) 2 ], the Zn II cation is located on an inversion center and is coordinated by two 4-formylbenzoate anions, two N , N -diethylnicotinamide (DENA) ligands and two water molecules. The four O atoms in the equatorial plane around the Zn II cation form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxylate group and the adjacent benzene ring is 2.96 (11)°, while the pyridine ring and the benzene ring are oriented at a dihedral angle of 79.26 (4)°. The coordinating water molecule links with the carboxylate group via an intramolecular O—H...O hydrogen bond. In the crystal, O—H...O and weak C—H...O hydrogen bonds link the molecules into a three-dimensional supramolecular network. A π–π contact between the parallel pyridine rings of adjacent molecules may further stabilize the crystal structure [centroid–centroid distance = 3.5654 (8) Å].
