Title: Materials Data on Sr2NdCu3(PbO4)2 by Materials Project

Abstract

Pb2Sr2NdCu3O8 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.64–2.81 Å. Nd3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.48–2.51 Å. There are two inequivalent Cu+1.67+ sites. In the first Cu+1.67+ site, Cu+1.67+ is bonded to five O2- atoms to form CuO5 square pyramids that share a cornercorner with one PbO5 square pyramid and corners with four equivalent CuO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.95–2.30 Å. In the second Cu+1.67+ site, Cu+1.67+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.87 Å. Pb2+ is bonded to five O2- atoms to form distorted PbO5 square pyramids that share a cornercorner with one CuO5 square pyramid, corners with four equivalent PbO5 square pyramids, and edges with four equivalent PbO5 square pyramids. There are a spread of Pb–O bond distances ranging from 2.19–3.11 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to fourmore » equivalent Sr2+, one Cu+1.67+, and one Pb2+ atom to form distorted OSr4CuPb octahedra that share corners with eight OSr4CuPb octahedra, edges with four equivalent OSr4CuPb octahedra, and faces with two equivalent OSr2Nd2Cu2 octahedra. The corner-sharing octahedra tilt angles range from 20–53°. In the second O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Sr2+, two equivalent Nd3+, and two equivalent Cu+1.67+ atoms. In the third O2- site, O2- is bonded to two equivalent Sr2+, two equivalent Nd3+, and two equivalent Cu+1.67+ atoms to form distorted OSr2Nd2Cu2 octahedra that share corners with eight OSr4CuPb octahedra, edges with three equivalent OSr2Nd2Cu2 octahedra, and faces with two equivalent OSr4CuPb octahedra. The corner-sharing octahedra tilt angles range from 0–53°. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, one Cu+1.67+, and four equivalent Pb2+ atoms.« less
