title: Poly[bis-{μ-N'-[(pyridin-4-yl)methyl-idene]benzohydrazidato}copper(II)].
abstract: In the title complex, [Cu(C13H10N3O)2] n , the copper(II) cation is located on a crystallographic inversion centre and adopts an elongated octa-hedral coordination geometry with the equatorial plane provided by trans-arranged bis-N,O-chelating acyl-hydrazine groups from two ligands and the apices by the N atoms of two pyridine rings belonging to symmetry-related ligands. The ligand adopts a Z conformation about the C=N double bond. The dihedral angle between the pyridine and phenyl rings is 2.99 (13)°. An intra-ligand C-H⋯N hydrogen bond is observed. In the crystal, each ligand bridges two adjacent metal ions, forming a (4,4) grid layered structure. π-π stacking inter-actions [centroid-centroid distances in the range 3.569 (4)-3.584 (9) Å] involving rings of adjacent layers result in the formation of a three-dimensional supra-molecular network.
