摘要
3-(3-吡啶基)丙烯酸(3-HPYA)配体与稀土金属离子钆(Gd)通过水热法合成了一种新的一维链状配位聚合物[Gd(3-HPYA)3(H2O)]n(1),其结构经IR,热重分析,元素分析和X-射衍单晶衍射仪表征。1属于三斜晶系,空间群P-1,晶胞参数为:a=0.619 43(15)nm,b=1.270 00(3)nm,c=1.563 40(4)nm,α=111.728(4)°,β=90.330(4)°,γ=95.202(4)°,Z=2。1通过分子间的氢键堆积为三维网状结构。对1的热稳定性进行了研究。
A novel coordination ploymer, [Gd（3-HPYA）3 （H2O） ]n, was synthesized by the hydrothermal reaction between 3-（3-pyridyl） acrylate acid（3-HPYA） and Gd（ NO3 ） 3 ·6H2O. The structure was characterized by IR, TG, elemental analysis and single-crystal X-ray diffraction. The crystal of 1 belongs to triclinic, space group P-1 with a = 0. 619 43 （ 15 ） nm, b = 1. 270 00 （3） nm, c = 1.563 40（4） nm, α = 111.728（4）°,β=90.330（4）°, γ=95.202（4）°, Z=2, Mr =619.68, Dc = 1. 810 g. cm^-3. The final R1 =0.031 0 and wR2 =0.059 2 for 3 889 observed reflections with 1〉2σ（1）. The structural analysis showed that 1 complex has one-dimensional structure, and the three-dimensional nets are constructed by hydrogen bonds.
