title: [2,2'-(1,1'-Binaphthyl-2,2'-diyldiimino)-diethanol-κN,N',O]dichloridocopper(II).
abstract: In the title complex, [CuCl(2)(C(24)H(24)N(2)O(2))], the Cu(II) cation is N,N',O-chelated by a 2,2'-(1,1'-binaphthyl-2,2'-diyldiimino)-diethanol ligand and coordinated by two chloride anions in a distorted square-pyramidal geometry. In the diethanol ligand, the two naphthalene ring systems are twisted with respect to each other at a dihedral angle of 68.30 (9)°. The uncoord-inated hy-droxy group links with a coordinated chloride anion via an intra-molecular O-H⋯Cl hydrogen bond. Inter-molecular N-H⋯O and N-H⋯Cl hydrogen bonds occur in the crystal structure.
