In the crystal structure of the title compound, [Zn(C18H14NO2)2].C2H6O, the Zn atom displays a highly distorted octahedral coordination involving the O and N atoms of two molecules of the Schiff base 1-[N-(2-methoxyphenyl)iminomethyl]naphthalen-2(1H)-one, which acts as an O,N,O'-tridentate ligand. The ethanol molecule is bound to the methoxy group of one ligand molecule via a hydrogen bond.
