Crystal structure and Hirshfeld surface analysis of (1H-imidazole-jN³)[N-(2-oxidobenzylidene)-tyrosinato-j³O,N,O0 ]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]
