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 [Zn-2(dpatrz)(2)Cl-4] (I) and a linear trinuclear complex, [Cd-3(dpatrz)(4)(N-3)(2)Cl-4] (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) angstrom, V = 2743.4(9) angstrom(3), Z = 4, C16H32N8Cl4Zn2, M-r = 609.4, D-c = 1.475 g.cm(3), mu = 2.16 mm(-1), F(000) = 1248, GOOF = 1.091, the final R = 0.0295 and wR = 0.0665 for 1999 observed reflections (I > 2 sigma(I)). Complex II crystallizes in monoclinic, space group P2(1)/c with a = 11.408(2), b = 15.211(3), c = 18.152(6) angstrom, beta = 123.75(2)degrees, V = 2619.1(1) angstrom(3), Z = 2, C32H64N22Cl4Cd3, M-r = 1236.05, D-c = 1.567 g.cm(3), mu = 1.46 mm(-1), F(000) = 1244, GOOF = 1.042, the final R = 0.0444 and wR = 0.0913 for 3466 observed reflections (I > 2 sigma(I)). The analysis of X-ray revealed that both structures lie about the inversion centers: complex I adopts two mu(1,2)-triazole bridges linking two Zn(II) ions and II forms a linear trinuclear structure with four mu(1,2)-triazoles and two mu(1,1)-N-3(-) 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 (tau = 0.34). The hydrogen bonds of C-H center dot center dot center dot Cl and N-H center dot center dot center dot Cl lead to the discretes into a 3D supramolecular network in both compounds. The thermal stabilities and photoluminescence behaviors of them were also studied.
