Abstract
A series of coordination polymers based on 3,5-dinitrosalicylic acid (H2sal) and nine flexible bis(triazole) ligands, namely, [Cu4(sal)4(L1)2(H2O)]·2H2O (1), [Cu4(sal)4(L2)2(H2O)] (2), [Cu2(sal)2(L3)(H2O)] (3), [Cu2(sal)2(L4)(H2O)] (4), [Cu5(sal)4(OH)2(L5)2(H2O)3]·H2O (5), [Cu(sal)(L6)] (6), [Cu2(sal)2(L7)] (7), [Cu(sal)(L8)]·0.5H2O (8), [Cd2(sal)2(L1)(H2O)2] (9), [Cd2(sal)2(L7)3] (10) and [Cd4(sal)4(L9)4] (11), where L1 = 1,2-bis(1,2,4-triazol-1-yl)ethane, L2 = 1,3-bis(1,2,4-triazol-1-yl)propane, L3 = 1,4-bis(1,2,4-triazol-1-yl)butane, L4 = 1,5-bis(1,2,4-triazol-1-yl)pentane, L5 = 1,5-bis(1,3,4-triazol-1-yl)pentane, L6 = 1,6-bis(1,2,4-triazol-1-yl)hexane, L7 = 1,10-bis(1,2,4-triazol-1-yl)decane, L8 = 1,4-bis((1H-1,2,4-triazol-1-yl)methyl)benzene and L9 = 1,1′-(2,2′-oxybis(ethane-2,1-diyl))bis(1H-1,2,4-triazole), have been synthesized and characterized by single crystal X-ray diffraction, elemental analyses, IR spectra, PXRD spectra and TG analysis. Compounds 1 and 4 possess one-dimensional (1D) double chains. Compounds 2, 3 and 5 show two-dimensional (2D) 44 networks. Compound 6 displays a three-dimensional (3D) uninodal eight-connected self-penetrating framework with the 42068 topology. Compound 7 reveals a 2D 2-fold interpenetrating 44-sql network. Compounds 8 and 9 display 2D undulated layers. Compound 10 shows a 1D chain. Compound 11 reveals a discrete tetranuclear cluster. The UV-vis spectra and optical energy gap of 1–11 have also been investigated in detail.
