Abstract

In the title hetero-dinuclear complex, [CuSm(C22H24N2O4)Cl3(CH3OH)2], the CuII cation is N,N′,O,O′-chelated by a 6,6′-dimeth­oxy-2,2′-[cyclo­hexane-1,2-diylbis(nitrilo­methanylyl­idene)]diphenolate ligand, and one Cl− anion further coordinates to the CuII cation to complete the distorted square-pyramidal coordination geometry, while the SmIII cation is chelated by four O atoms from the same ligand, and is further coordinated by two methanol mol­ecules and two Cl− anions in an bicapped trigonal–prismatic geometry. Intra- and inter­molecular O—H⋯Cl hydrogen bonds are present in the structure.
