Crystal Structure of Bis[acetone-1-naphthoylhydrazinato(−1)]copper(II) and Investigations of Intermolecular Interactions

In the crystal structure of the bis(acetone‐1‐naphthoylhydrazinato)copper(II) complex there are interactions of neighbouring molecules via naphthyl groups; the naphthyl group of one molecule interacts with the copper centre and CH3 group of another molecule. The geometry of the crystal structure and dispositions of charges in the naphthyl and chelate rings indicate that there are stacking interactions between the aromatic ring and, not only the copper atom, but also the whole chelate ring.
