The asymmetric unit of the title complex, [Zn(C8H 7O3)2(C6H6N 2O)2], contains three crystallographically independent molecules with similar configurations. The ZnII cation is coordinated by two N atoms of two nicotinamide ligands and three O atoms from two 4-methoxybenzoate anions in a distorted trigonalbipyramidal geometry. In each independent molecule, one Zn-O bond distance [2.5181 (12), 2.5931 (12) and 2.4085 (12) Å for the three molecules] is significantly longer than the other two. In the crystal structure, extensive N-H?O and C-H?O hydrogen bonding links the molecules into a three-dimensional network. ?-? contacts between the pyridine rings and between the pyridine and benzene rings [centroid-centroid distances = 3.7655 (9) and 3.8453 (10) Å, respectively] further stabilize the crystal structure.
