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

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. [ABSTRACT FROM AUTHOR]
