The Schiff base condensation reaction between precursor diamine N,N'-bis(2-aminophenyl)-pyridine-2,6-dicarboxamide and 1,8-naphthyridine-2-carbaldehyde yielded a racemic compound (L^P/L^M), which was characterized by ¹H/¹³C NMR, infrared spectroscopy, elemental analysis, single crystal X-ray diffraction. Three complexes, [Hg₂LI₄] (1), [Hg₂LBr₄] (2), [Hg₂L₂Cl₄]‧2H₂O (3) with different coordination configurations were obtained from the of this HgX₂ (X = I⁻, Br⁻, Cl⁻), respectively, their structures geometries determined via diffraction techniques. Both 1 2 exist as dinuclear complexes 1:2 molar ratio L Hg(II), while 3 exists 44-membered metallamacrocycle 1:1 Hg(II). structural diversity these three indicates that counter anions have significant effects on topology. In addition, solid-state luminescence gas adsorption towards methanol vapor at room temperature investigated.

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.
