| 摘 要： | Reaction of ZnCl2 and 4-amino-3,5-propyl-1,2,4-triazole(dpatrz) or CdCl2, NaN3 and dpatrz, in aqueous solution at room temperature yields two neutral clusters: a dinuclear complex Zn2(dpatrz)2Cl4](I) and a linear trinuclear complex, Cd3(dpatrz)4(N3)2Cl4](Ⅱ). Both complexes have been characterized by X-ray single-crystal diffraction, powder XRD, IR, elemental analysis, TG and fluorescence analysis. Complex I crystallizes in orthorhombic, space group Pbca with a = 11.865(2), b = 14.464(3), c = 15.985(3) , V = 2743.4(9) 3, Z = 4, C16H32N8Cl4Zn2, Mr = 609.4, Dc = 1.475 g·cm3, μ = 2.16 mm-1, F(000) = 1248, GOOF = 1.091, the final R = 0.0295 and wR = 0.0665 for 1999 observed reflections(I 2σ(I)). Complex Ⅱ crystallizes in monoclinic, space group P21/c with a = 11.408(2), b = 15.211(3), c = 18.152(6) , β = 123.75(2)o, V = 2619.1(1) 3, Z = 2, C32H64N22Cl4Cd3, Mr = 1236.05, Dc = 1.567 g·cm3, μ = 1.46 mm-1, F(000) = 1244, GOOF = 1.042, the final R = 0.0444 and wR = 0.0913 for 3466 observed reflections(I 2σ(I)). The analysis of X-ray revealed that both structures lie about the inversion centers: complex I adopts two μ1,2-triazole bridges linking two Zn(Ⅱ) ions and Ⅱ forms a linear trinuclear structure with four μ1,2-triazoles and two μ1,1-N3- bridging modes. There are different coordinated geometries for three Cd(Ⅱ) ions in Ⅱ: one is coordinated with an octahedral environment, and the other two are distorted tetragonal pyramids(τ = 0.34). The hydrogen bonds of C–H···Cl and N–H···Cl lead to the discretes into a 3D supramolecular network in both compounds. The thermal stabilities and photoluminescence behaviors of them were also studied. |
