Title: Materials Data on Cu3Pb2Se2(NO7)2 by Materials Project

Abstract

Cu3Pb2(SeO4)2(NO3)2 crystallizes in the orthorhombic Cmc2_1 space group. The structure is two-dimensional and consists of eight nitric acid molecules and two Cu3Pb2(SeO4)2 sheets oriented in the (0, 0, 1) direction. In each Cu3Pb2(SeO4)2 sheet, there are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.92–1.99 Å. In the second Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.95–1.97 Å. There are two inequivalent Pb4+ sites. In the first Pb4+ site, Pb4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.42–2.54 Å. In the second Pb4+ site, Pb4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.47–2.54 Å. There are two inequivalent Se2+ sites. In the first Se2+ site, Se2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. All Se–O bond lengths are 1.74 Å. In the second Se2+ site, Se2+ is bonded in amore » trigonal non-coplanar geometry to three O2- atoms. All Se–O bond lengths are 1.74 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to three Cu2+ and one Pb4+ atom to form distorted corner-sharing OCu3Pb tetrahedra. In the second O2- site, O2- is bonded to three Cu2+ and one Pb4+ atom to form distorted corner-sharing OCu3Pb tetrahedra. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cu2+, one Pb4+, and one Se2+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Cu2+, one Pb4+, and one Se2+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cu2+, one Pb4+, and one Se2+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Cu2+, one Pb4+, and one Se2+ atom.« less
