title: Bis(4-meth-oxy-benzoato)-κO,O';κO-bis-(nicotinamide-κN)zinc(II).
abstract: The asymmetric unit of the title complex, [Zn(C(8)H(7)O(3))(2)(C(6)H(6)N(2)O)(2)], contains three crystallographically independent mol-ecules with similar configurations. The Zn(II) cation is coordinated by two N atoms of two nicotinamide ligands and three O atoms from two 4-meth-oxy-benzoate anions in a distorted trigonal-bipyramidal geometry. In each independent mol-ecule, one Zn-O bond distance [2.5181 (12), 2.5931 (12) and 2.4085 (12) Å for the three mol-ecules] is significantly longer than the other two. In the crystal structure, extensive N-H⋯O and C-H⋯O hydrogen bonding links the mol-ecules 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.
