A new layered indium selenium oxychloride material Synthesis, structure, and characterization of InSeO3Cl

Abstract

A new layered indium selenium oxychloride material InSeO3Cl has been synthesized by a standard solid-state reaction using In2O3 InCl3 and SeO2 as reagents Single-crystal X-ray diffraction was used to determine the structure of the reported material InSeO3Cl crystallizes in the orthorhombic space group Pbca (No 61) with a = 70580(14) A b = 70390(14)A c = 16206(3)A V = 8051(3) A(3) and Z = 8 InSeO3Cl has a layered structure consisting of distorted InO4Cl2 octahedra and SeO3 polyhedra The Se4+ cations are in asymmetric coordination environment attributed to their stereoactive lone pairs The Ione pairs on the Se4+ cations approximately point In the [101] [-10-1] [10-1] and [-101] direction A separation of the halophile and the chalcophile moieties is observed from the reported material Detailed structural analysis with full characterization including infrared spectroscopy bond valence calculations thermogravimetric analysis elemental analysis and dipole moment calculations are reported (C) 2010 Elsevier Masson SAS All rights reserved
