✦ Synopsis

A new microporous iron(Ill) phosphate, [H3N(CH2)4NH313-[Fe8(HPO4)12(PO4)2(H20)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 P3 (No.147) with a = b = 13.495(2) A, c = 9.396(2) A., V = 1481.9(4) A 3 and Z = 4 with R/Rw = 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(H20)6].
