Crystal structure and Hirshfeld surface analysis of (aqua-κO)(methanol-κO)[N-(2-oxidobenzylidene)threoninato-κ3 O,N,O′]copper(II)

Abstract

In the title complex molecule, [Cu(C11H11NO4)(CH4O)(H2O)], the Cu atom is coordinated in a distorted square-pyramidal geometry by a tridentate ligand synthesized from L-threonine and salicylaldehyde, one methanol molecule and one water molecule. In the crystal, the molecules show intra- and intermolecular O—H...O hydrogen bonds. The Hirshfeld surface analysis indicates that the most important contributions to the packing are H...H (49.4%) and H...O/O...H (31.3%) contacts.
