Abstract

Pb3Te2(O3Br)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 4-coordinate geometry to four O2- and four Br1- atoms. There are two shorter (2.46 Å) and two longer (2.65 Å) Pb–O bond lengths. There are one shorter (3.34 Å) and three longer (3.39 Å) Pb–Br bond lengths. In the second Pb2+ site, Pb2+ is bonded in a 5-coordinate geometry to five O2- and three Br1- atoms. There are a spread of Pb–O bond distances ranging from 2.44–2.71 Å. All Pb–Br bond lengths are 3.45 Å. In the third Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to eight O2- and one Br1- atom. There are a spread of Pb–O bond distances ranging from 2.57–3.06 Å. The Pb–Br bond length is 3.40 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded to four O2- atoms to form distorted edge-sharing TeO4 trigonal pyramids. There are two shorter (1.96 Å) and two longer (2.09 Å) Te–O bond lengths. In the second Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- and one Br1- atom. Theremore »« less
