The title compound, [Zn2(CH3COO)4(C6H6N2O)2]·2H2O, crystallized in the triclinic space group P1, with cell parameters a = 10.918(2)Å, b = 10.894(2)Å, c = 8.2112(9)Å, α = 88.22(1)°, β = 92.89(1)°, γ = 42.443(7)Å and Z = 1. The acetato ligands serve to bridge the two Zn(II) centres, while nicotinamide behaves as a monodentate ligand. Coordination of the metal centre to nicotinamide occurs through the lone pair residing on the pyridine ring nitrogen. Crystalline water participates in hydrogen bonding to the O atom of nicotinamide. The geometry around Zn(II) is a distorted square pyramidal form in nature.
