title: A dinuclear zinc complex with (E)-4-dimethyl-amino-N'-(2-hy-droxy-benzyl-idene)benzohydrazide.
abstract: The title compound, bis-[μ-(E)-2-({2-[4-(dimethyl-amino)-benzo-yl]hydrazinyl-idene}meth-yl)phenolato]bis-[formato-zinc], [Zn(2)(C(16)H(16)N(3)O(2))(2)(CHO(2))(2)], is a dinuclear Zn(II) complex containing two Zn(II) cations, two monovalent anions of a Schiff base ligand, 4-dimethyl-amino-N'-(2-hy-droxy-benzyl-idene)benzohydrazide (L), and two formate ions. Each Zn(II) atom chelates with the hy-droxy O atom of salicyl-aldehyde, the imine N atom, the carbonyl O atom, the formate carboxyl-ate O atom and the hy-droxy O atom of the salicyl-aldehyde moiety in a symmetry-related unit. The five-coordinate Zn(II) atoms form a dimeric centrosymmetric unit with a central parallelepiped Zn(2)O(2) core and parallel faces derived from the Schiff base ligands. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds between the amide N atom and the formate carboxyl-ate O atom.
