Crystal structure of bis­[4-(all­yloxy)-N′-(but-2-en-1-yl­idene)benzohydrazidato]nickel(II)

In the title complex, [Ni(C(14)H(15)N(2)O(2))(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 mol­ecule 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 inter­actions that form a di-periodic layered network.
