摘要
Three cadmium(II)-halide complexes with 5-(ethylthio)-1H-tetrazole (Hett) as ligand, namely [Cd7Cl2(ett)12(H2O)2] n (1), [Cd-2(OH) Br(ett)2](n) (2) and [Cd-2(OH) I(ett)(2)](n) (3), have been hydrothermally synthesized and characterized. Complex 1 was synthesized at pH = 7 and exhibits a 3D supramolecular framework, where the adjacent Cd ions form a tetrahedron unit by ett ligands bridge and the tetrahedron units share vertices to connect each other by ett bridges to form a 2D layer architecture, which is further interlinked by mu(2)-Cl to form 3D structures. Complexes 2 and 3 are isostructural, generated at pH = 8.0 similar to 9.0, displaying similar 2D networks via ett ligands and different halide ions (Br- in 2, I- in 3, respectively). In addition, thermal stabilities and luminescent properties of new complexes 1 similar to 3 have been studied.
