- Abstract
The zinc(II) pseudohalide complexes {[Zn(L334)(SCN)2(H2O)](H2O)2} n ( 1) and [Zn(L334)(dca)2] n ( 2) were synthesized and characterized using the ligand 3,4-bis(3-pyridyl)-5-(4-pyridyl)-1,2,4-triazole (L334) and ZnCl2 in presence of thiocyanate (SCN-) and dicynamide [dca, N(CN)2-] respectively. Single-crystal X-ray structural analysis revealed that the central ZnII atoms in both complexes have similar octahedral arrangement. Compound 1 has a 2D sheet structure bridged by bidentate L334 and double μN,S-thiocyanate anions, whereas complex 2, incorporating with two monodentate dicynamide anions, displays a two-dimensional coordination framework bridged by tetradentate L334 ligand. Structural analysis demonstrated that the influence of pseudohalide anions plays an important role in determining the resultant structure. Both complexes were characterized by IR spectroscopy, microanalysis, and powder X-ray diffraction techniques. In addition, the solid fluorescence and thermal stability properties of both complexes were investigated.
