Popis: | Four CdII coordination polymers, namely {[Cd(L334)(Cl)2](CH3OH)}n (1), [Cd(L334)(Cl)(dca)]n (2), {[Cd(L334)(Cl)1.33(N3)0.67](H2O)}n (3), and {[Cd(L334)(SCN)2(H2O)](H2O)1.5(CH3OH)}n (4), have been synthesized by the conventional reactions of CdCl2 and 3,4-bis(3-pyridyl)-5-(4-pyridyl)-1,2,4-triazole (L334) or in the presence of different pseudohalides dicyanamide (dca), azide (N3), and thiocyanate (SCN), respectively as auxiliary ligands. Complexes 1–3 exhibit the isostructural 2D layered network structures, whereas complex 4 shows a distinct 2D network with dimeric CdII subunits. The structural discrepancy in 1–4 indicates the significant influence of pseudohalide anions on the structural assembly of CdII coordination polymers with 3,4-bis(3-pyridyl)-5-(4-pyridyl)-1,2,4-triazole. In addition, thermogravimetric and fluorescent properties for all complexes and the ligand have also been investigated. |
