Abstract
Two bidentate-bridging propionate ligands connect two Zn-II atoms [Zn- O(3) 2.040(8) and Zn-O(4)(-x, -y, -z) 2.059(4)Angstrom] forming a dime ric [Zn-2(C3H5O2)(4)(C6H6N2O)(4)] complex. The coordination around eac h Zn-II atom is trigonal bipyramidal. A monodentate propionate anion c ompletes the trigonal basal plane [Zn-O(1) 2.072(3)Angstrom] and two u nidentate nicotinamide ligands occupy the apical positions [Zn-N(11) 2 .192(5) and Zn-N(21) 2.174(4)Angstrom] of the coordination sphere of e ach Zn-II atom. The Zn ... Zn distance is 3.900 (1) Angstrom.
