Özet

The asymmetric unit of the title complex, [Zn(C8H7O3)(2)-(C6H6N2O)(2)], contains three crystallographically independent molecules with similar configurations. The Zn-II 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) angstrom for the three molecules] is significantly longer than the other two. In the crystal structure, extensive N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonding links the molecules into a three-dimensional network. pi-pi contacts between the pyridine rings and between the pyridine and benzene rings [centroid-centroid distances = 3.7655 (9) and 3.8453 (10) angstrom, respectively] further stabilize the crystal structure.
