中文摘要：

在水热条件下，利用CaCl2和哌嗪（哌嗪=PPZ）在水溶液中反应，合成了一维配位聚合物[Cd（HPPZ）Cl3]·H2O．该分子中Cl^-双桥连Ca（Ⅱ）形成一维直线型链，而PPZ通过1个N原子与1个Ca（Ⅱ）配位，交替悬挂在链的两端．链与链之间通过N—H…o和o-H…Cl氢键作用形成三维超分子网络．结果表明：该配位聚合物属于正交晶系，Pnma空间群；晶胞参数a=0．7753（5）nm，b=0．9909（2）nm，c=1．3377（4）nm，V=1．0278（01）mn^3，Z=4，最后一致性因子[I〉2σ（I）]，R1=0．0277，ωR2=0．0712．

英文摘要：

A novel 1-D transition metal coordination polymers [ Cd （ HPIPZ） Cl3 ]·H2O, （ PIPZ = piperazine ） has been hydrothermally synthesized and characterized by means of elemental analyses and single crystal X- ray diffraction. Chlorine Ions doubly bridge the Cd（ Ⅱ ） to form a 1-D Chain, HPIPZ molecules are attached to thel-D chain as branches of the chain by coordinating to the Cd（ Ⅱ ）. 3-D supramolecular network was formed through N--H…O and O-H…Cl hydrogen bond interactions between chains. The crystallographic data are crystallized in Monoclinic with group Pnma, a = 0. 775 3（5） nm, b = 0. 990 9 （2） nm, c = 1. 337 7 （4） nm, V = 1. 027 8 （01 ） nm^3, Z = 4, R 1 = 0. 027 7, ωR 2 = 0.071 2 [ I 〉 2σ （ I ） ]. Moreover, the spectral properties and TGA spectrum have been further studied and discussed.
