Abstract
In the title complex, [Cu(C14H14NO2)2], the discrete complex molecules have crystallographic inversion symmetry. The slightly distorted square-planar coordination sphere of the CuII atom comprises two phenolate O atoms and two oxime N atoms from two bidentate–chelate 2-[1-(ethoxyimino)ethyl]-1-naphtholate O-ethyl oxime (L −) ligands [Cu—O = 1.8919 (17) Å and Cu—N = 1.988 (2) Å]. The two naphthalene ring systems in the molecule are parallel, with a perpendicular interplanar spacing of 1.473 (2) Å, while each complex unit forms links to four other molecules via intermolecular methyl C—H⋯π interactions, giving an infinite cross-linked layered supramolecular structure
