Two cadmiun coordination polymers Cd ( AmTAZ ) C1 ( 1 ) and [ Cd ( AmTAZ ) ( BDC ) ( H2O ) 2 ] · 1.25H2O(2) (AmTAZH = 3-amino-1,2,4-triazole, H2BDC = benzene-1, 4-dicarboxylic acid) were synthesized under hydrothermal in stiu conditions and characterized by IR, TG-DTA, CHN elemental analysis and single crystal X-ray diffraction analysis. The fluorescent properties of compounds 1 and 2 are also discussed. Compound 1 crystallizes in the triclinic space group P2 ( 1 ) 2 ( 1 ) 2 ( 1 ) with a = 0. 6452 ( 3 ) nm, b = 0. 7848 (5) nm, c = 1. 0449 (6) nm, V = 0. 5291 (5) nm^3, Z = 4, R1 = 0. 0226, wRz = 0. 0377, GOF = 1. 087. Compound 2 crystallizes in the orthorhombic space group Pmc2( 1 ) with a =0. 7100 nm, b =0. 9920 nm, c = 1.2561 nm, V=0.8847 nm^3, Z=8, R1 =0.0934, wR2 =0.2456, GOF=1.031.
