摘要 报道一个在水热条件下合成得到的刚性有机胺(质子化的三乙烯二胺)导向的新颖杂化聚合物{[(H2TEDA)(PbI3)NO3].H2O}n(1).用X-射线衍射进行结构确定,并对其进行红外、紫外光谱表征.结构解析表明,标题物晶体属于正交晶系,Pbam空间群,晶胞参数为a=26.884(5)nm,b=7.842 0(16)nm,c=0.951 11(19)nm,V=2.005 2(7)nm3,Z=1,Dc=2.485 mg.m-3,F(000)=1 312,μ(Mokα)=13.026mm-1,最终偏离因子R1=0.065 5,wR2=0.185 4.标题物整个结构由质子化的三乙烯二胺阳离子、一维(PbI3)nn-聚阴离子链以及NO3-离子和水分子组成,其中聚阴离子链(PbI3)nn-由PbI6八面体反式共面形成,NO3-离子和水分子作为抗衡离子和空间填充分子堆积在晶胞内,它们之间靠静电作用结合在一起.还对标题化合物进行了光学带隙测试,结果表明,其带隙为2.38 eV,属于半导体. Reports on the hydrothermal preparation of the new hybrid polymer {[(H2TEDA)(PbI3)NO3]·H2O}n(1) directed by rigid organic amine.It has been characterized by X-ray single diffraction,IR and UV-Vis spectra.The title compound crystallizes in triclinic system,space group Pbam with a =26.884(5) nm,b = 7.842 0(16) nm,c =0.951 11(19) nm,V=2.005 2(7) nm3,Z=1,Dc=2.485 mg·m-3,F(000)= 1 312,μ(Mokα)= 13.026 mm-1,the final R1 = 0.065 5,wR2=0.185 4.The structure of(1) consists of the diprotonated organic amine(H2TEDA2+) and anionic infinite chain(PbI3)n-n.The(PbI3)n-n chain is generated from trans-face-sharing of the PbI6 octahedra.NO-3 and H2O in the crystal act as counteractions and packing molecules,respectively.Its optical gap of 2.38 eV indicates it semiconducta nataye.
