A bis-chelate

The copper(II) atom in the mol­ecular title complex has a distorted square-pyramidal coordination environment by three O and two N atoms from a bidentate and a tridentate ligand.
The mol­ecular bis-chelate complex (2-{[(2-hy­droxy­ethyl-κO)amino-κN]meth­yl}-6-meth­oxy­phenolato-κO)(2-{[(2-hy­droxy­eth­yl)imino-κN]meth­yl}-6-meth­oxy­phenolato-κO)copper(II), [Cu(C10H14NO3)(C10H12NO3)] or [Cu(HL im)(HL am); HL im = C10H14NO3; HL am = C10H12NO3, represents the first compound containing a salicyl­idene-2-ethano­lamine type ligand in both imino HL im (Schiff base) and amino HL am (reduced Schiff base) forms that has been structurally characterized on the basis of X-ray data. Two mol­ecules of the monodeprotonated ligands coordinate the CuII ion in an (N,O phen)-bidentate and an (N,O phen,O alc)-tridentate fashion in the case of the imino and amino forms, respectively. The shape of the CuN2O3 coordination polyhedron is a distorted square-pyramid (geometry index τ5 = 0.26). Inter­molecular N—H⋯O and O—H⋯O hydrogen bonds, involving H atoms of the amino and hy­droxy­ethyl groups, create a two-dimensional supra­molecular array extending parallel to (010).
