摘要：

Hydrothermal reaction of Cd(OAc)2, 4-amino-3,5-bis(2-pyridyl)-1,2,4-triazole(2-bpt) and tetrabromoterephthalic acid(H2tbta) yields a novel layered network {[Cd(2-bpt)(tbta)](H2O)3}n(1), which has been structurally determined by single-crystal X-ray diffraction. Complex 1 crystallizes in triclinic, space group P1 with a = 9.384(3), b = 10.652(3), c = 14.096(4), a = 78.616(4), β = 87.101(5), γ = 86.555(5)°, V = 1377.7(6)3, Z = 2, Mr = 884.43, Dc = 2.132 g/cm3, F(000) = 844, μ = 6.644 mm-1, R = 0.0461 and w R = 0.1173. The adjacent CdII centers are connected via two 2-bpt molecules to form a 6-membered bimetallic ring, and such rings are further bridged via tbta2– ligands to afford an infinite 2D coordination framework. Besides, these adjacent layers are extended to the resultant 3D supramolecular network via H-bonding interactions. In addition, the thermal stability and fluorescent properties of complex 1 have also been investigated.
