Synthesis, Crystal Structures, and Alcohol Vapor Adsorption Properties of Cd(Ii) and Cu(Ii) Complexes Based on a Bis(Salicylaldehyde Acylhydrazone) Schiff Base

Published: Jan. 1, 2024

A bis(salicylaldehyde acylhydrazone) Schiff base ligand (H4L) was designed and synthesized from the condensation reaction. Four complexes, formulated as {[Cd(H5L+)Cl3]·2CH3OH}n (1), {[Cd(H4L)Br2]·H2O}n (2), {[Cd2(H4L)2I4]·CH3OH}n (3), [Cu3(L4-)(Ac)2]·CH3OH·H2O (4) were characterized by single-crystal X-ray diffraction. Complex 1 exists a 2D sheet structure each Cd(II) ion in complex is six-coordinated with octahedral geometry. Both complexes 2 3 exist 1D zig-zag structures two five-coordinated trigonal bipyramidal 4 centrosymmetric trinuclear structure, which Cu(II) ions are square pyramidal geometry other The structural differences attributed to coordination ability of sites configurations metal ions. Furthermore, alcohol vapor adsorption measurements showed that all exhibited good capacities toward methanol vapor.
