Crystal structure of bis[4-(allyloxy)-N⁰-(but-2-en-1ylidene)benzohydrazidato]nickel(II)

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 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.
