Abstract

A new microporous iron (III) phosphate, [H₃N(CH₂)₄NH₃]₃[Fe₈(HPO₄)₁₂(PO₄)₂(H₂O)₆], has been prepared using low temperature hydrothermal methods and characterized by single-crystal X-ray diffraction, EDAX, infrared spectroscopy, thermogravimetric analysis and bond valence sums. The title compound crystallizes as light pink hexagonal-shaped tabs in the centrosymmetric hexagonal space group 3¯ (No.147) with a = b = 13.495(2) Å, c = 9.396(2) Å, V = 1481.9(4) Å³ and Z = 4 with R/R_w = 0.044/0.048. The compound exhibits a complicated three-dimensional microporous structure with quaternary ammonium ions acting as a template for the framework. It is similar to previously reported [HN(CH₂CH₂)₃NH]₃[Fe₈(HPO₄)₁₂(PO₄)₂(H₂O)₆].

三维微孔磷酸铁:[H3N(CH2)4NH3]3[Fe8(HPO4)12(PO4)2(H2O)6]的水热合成与结构测定

采用低温水热法制备了新型微孔磷酸铁(III) [H3N(CH2)4NH3]3[Fe8(HPO4)12(PO4)2(H2O)6]，并用单晶x射线衍射、EDAX、红外光谱、热重分析和键价和对其进行了表征。标题化合物在中心对称的六角形空间群3¯(No.147)中结晶为浅粉色的六角形标签，a = b = 13.495(2) Å， c = 9.396(2) Å， V = 1481.9(4) Å3, Z = 4, R/Rw = 0.044/0.048。该化合物具有复杂的三维微孔结构，季铵离子作为骨架模板。它类似于先前报道的[HN(CH2CH2)3NH]3[Fe8(HPO4)12(PO4)2(H2O)6]。
