Crystal structure and Hirshfeld surface analysis of aqua-(1H-imidazole-κN (3))[N-(2-oxido-benzyl-idene)threonato-κ(3) O,N,O']zinc(II).

The title complex, [Zn(C(11)H(11)NO(4))(C(3)H(4)N(2))(H(2)O)], which includes a tridentate ligand, was synthesized from l-threonine and salicyl-aldehyde. One water mol-ecule and one imidazole mol-ecule additionally coordinate the zinc(II) center in a distorted trigonal-bipyramidal geometry. The crystal structure features N-H⋯O and O-H⋯O hydrogen bonds. A Hirshfeld surface analysis indicates that the most important contributions to the packing are from H⋯H/H⋯H (50.7%) and O⋯H/H⋯O (25.0%) contacts.
