Crystal structure of bis-[4-(all-yloxy)-N'-(but-2-en-1-yl-idene)benzohydrazidato]nickel(II).

Abstract

In the title complex, [Ni(C14H15N2O2)2], the nickel(II) atom exhibits a square-planar coordination geometry, being coordinated by two negatively charged N,O chelating ligands in a trans configuration, with the metal located on a crystallographic center of symmetry. The X-ray structural characterization showed the complex to be disordered over two orientations with refined occupancies of 0.898 (2) and 0.102 (2). The whole mol-ecule is close to planar, the five- and six-membered rings subtending a dihedral angle of 7.5 (2)°. The crystal packing is supported by C-H⋯π and C-H⋯O inter-actions that form a di-periodic layered network.
