Abstract
A new sodium indium phosphate Na6In4[P7O24(OH)(5)] (.) 4H(2)O was synthesized under a mild hydrothermal condition and its structure was determined by means of single-crystal X-ray diffraction methods. The title compound crystallizes in a hexagonal system, space group P6(3), with a = 0.950 23(5) nm, b = 0.950 23(5) nm, c = 1.694 2(2) nm, alpha = 90degrees, beta = 90degrees, gamma = 120degrees, V = 1.324 8(2) nm(3), Z = 8, structure refined to R = 0.052 8 and wR = 0.116 5 for 2 134 independent observed reflections. The three-dimensional network structure consists of helical chains formed by apex-sharing polyhedra. The connection of the chains results in 4- and 8-polyhedral rings and cages centered by three indium metal connecting oxygen atoms formed by three 4-rings. The three-connected oxygen atom is firstly observed in indium phosphate systems.
