Abstract
Two new mixed-ligand Zn(II) coordination polymers, namely {[Zn(dtb)(1,3-bdc)(H2O)2](H2O)}n (1) and {[Zn1.5(dtb)(1,3,5-btc)(H2O)5](H2O)}n (2) (dtb = 1,3-di-(1,2,4-triazole-4-yl)benzene, 1,3-H2bdc = 1,3- benzenedicarboxylic acid, 1,3,5-H3btc = 1,3,5-benzenetricarboxylic acid) are hydrothermally synthesized and characterized by elemental analyses, infrared spectroscopy, powder and single crystal X-ray diffraction analyses. Both complexes display 1D chain structures. The thermal stabilities and luminescence properties of compounds 1 and 2 are also investigated. Crystal data: 1. C18H18N6O7Zn, Mr = 495.75, triclinic, P-1, a = 10.0820(11) Å, b = 10.1833(11) Å, c = 11.2000(12) Å, α = 80.8680(10)°, β = 73.7290(10)°, γ = 63.4320(10)°, V = 986.52(18) Å3, Z = 2, R(F) = 0.0246, wR(F2) = 0.0664; 2. C19H23N6O12Zn1.5, Mr = 625.49, triclinic, P-1, a = 6.588(4) Å, b = 11.757(7) Å, c = 15.724(9) Å, α = 76.883(6)°, β = 86.094(7)°, γ = 75.989(7)°, V = 1150.8(12) Å3, Z = 2, R(F) = 0.0355, wR(F2) = 0.0822.
