The asymmetric unit of the title complex, [Zn(C8H7O3)2(C6H6N2O)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 trigonal-bipyramidal 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. π–π 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.
