Syntheses and characterizations of zinc(II) and copper(II) complexes with reduced Schiff base derived from salicylaldehyde and D,L-selenomethionine

Abstract: New zinc(II) and copper(II) complexes with a reduced Schiff-base ligand derived from D,L-selenomethionine and salicylaldehyde have been synthesized and characterized by elemental analysis, magnetic susceptibility, IR, and NMR measurements. The single-crystal X-ray structure of the Cu(II) complex reveals that this complex is a carboxylate-bridged dimer of dinuclear copper(II) subunits and all metal centers are five-coordinate with O 4 N donor sets in distorted square-pyramidal geometries. The Cu(II) complex con… Show more

“…In most cases, different solvent molecules are distributed statistically throughout the crystal (for methanol and ethanol, more than 270 references in the CCDC, version 5.44, June 2023), 10 or a disordering takes place if they are present in a single molecule. 11–18 Only in two dozen cases, the exact presence of MeOH and EtOH in one molecule has been recorded, 19–41 and the coexistence of two types of molecules with coordinated MeOH and EtOH respectively in the crystal structure—only in three cases. 42,43 Among these compounds, the most unusual was the Mo( vi ) complex, in which the centrosymmetric H-linked dimers were formed by molecules containing only MeOH or only EtOH, i.e.…”
