摘要 3-(4-吡啶基)丙烯酸(4-HPYA)和Nd(NO3)3通过水热法合成了一种新的一维链状配位聚合物[Nd(4-PYA)3(H2O)2]n(1),其结构经IR,元素分析和X-射线单晶衍射表征。1属三斜晶系,P-1空间群,晶胞参数:a=0.829 23(13)nm,b=1.272 60(2)nm,c=1.435 00(12)nm,α=112.371(2)°,β=98.856(3)°,γ=100.239(2)°,V=1.336 6(3)nm3,Mr=660.72,Z=2,Dc=1.642 g.cm-3,F(000)=662,μ=2.002mm-1,R1=0.052 3,wR2=0.141 9。1通过分子间氢键作用将一维链紧密堆积成三维网状结构。 A novel coordination ploymer,[Nd(4-PYA)3(H2O)2]n(1),was synthesized by hydrothermal reaction between 3-(4-pyridyl)acrylic acid(4-HPYA) and Nd(NO3)3.The structure was characterized by IR,elemental analysis and singlecrystal X-ray diffraction.1 belongs to triclinic,space group P-1 with a=0.829 23(13) nm,b=1.272 60(2) nm,c=1.435 00(12) nm,α=112.371(2)°,β=98.856(3)°,γ=100.239(2)°,V=1.336 6(3) nm3,Mr=660.72,Z=2,Dc=1.642 g·cm-3,F(000)= 662,μ=2.002 mm-1,R1=0.052 3,wR2=0.141 9.1 has one-dimensional structure and its three-dimensional nets are constructed by hydrogen bonds.
