Crystal structure and Hirshfeld surface analysis of (1H-imidazole-κN3)[N-(2-oxidobenzylidene)tyrosinato-κ3O,N,O′]copper(II)

Abstract

The title copper(II) complex, [Cu(C16H13NO4)(C3H4N2)], consists of a tridentate ligand synthesized from L-tyrosine and salicylaldehyde. One imidazole molecule is additionally coordinating to the copper(II) ion. The crystal structure features N—H...O, O—H...O and C—H...O hydrogen bonds. The Hirshfeld surface analysis indicates that the most important contributions to the packing are from H...H (37.9%), C...H (28.2%) and O...H/H...O (21.2%) contacts.
