一维链状硫酸铟的溶剂热合成与表征

在溶剂热条件下, 以三乙烯四胺(TETA)作为模板剂, 合成出具有一维链状结构的硫酸铟化合物(C6H22N4)0.5[In(OH)](SO4)2(1). 采用红外光谱、热重分析、ICP、元素分析、粉末X射线衍射及单晶X射线衍射等手段对其进行了表征. 结果表明, 化合物1属于单斜晶系, P2(1)/c空间群, a=1.05240(3) nm, b=1.36802(4) nm, c=0.75295(2) nm, β=101.558(2)°, V=1.06204(5) nm3, Z=4, R1=0.0368, wR2=0.0897, GOF=1.068. 其结构是由InO4(OH)2八面体和SO4四面体通过共顶点连接形成的一维阴离子Tancoite-type 链. 质子化的TETA阳离子通过与阴离子链中的O原子之间的氢键作用将一维链连接成为三维超分子结构.

Solvothermal Synthesis and Characterization of One-dimensional Chained Indium-Sulfate

A one-dimensional chained indium-sulfate (C6H22N4)0.5[In(OH)](SO4)2(1) was synthesized under solvothermal condition using triethylenetetramine(TETA) as the templated agent and characterized by IR spectroscopy, TG, ICP and elemental analyses, powder and single crystal X-ray diffraction analyses. Compound 1 crystallized in the monoclinic system, space group P2(1)/c with a=1.05240(3) nm, b=1.36802(4) nm, c=0.75295(2) nm, β=101.558(2)°, V=1.06204(5) nm3, Z=4, R1 =0.0368, wR2=0.0897, GOF=1.068. Its structure is built up by InO4(OH)2 octahedra and SO4 tetrahedra by sharing their vertices to generate an one-dimensional anionic Tancoite-type chain. The one-dimensional chains are extended into three-dimensional supramolecular structure through the hydrogen bond interactions among the N atoms of TETA cations and O atoms of the anionic chains.
