Abstract

Sr8Ca3NdCu8Tl2(PbO14)2 crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.63–2.76 Å. In the second Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.63–2.75 Å. In the third Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.59–2.75 Å. There are two inequivalent Ca2+ sites.

The corner-sharing octahedra tilt angles range from 0–52°. In the third O2- site, O2- is bonded to two Sr2+, two equivalent Tl3+, and two equivalent Pb4+ atoms to form OSr2Tl2Pb2 octahedra that share corners with twelve OSr2Tl2Pb2 octahedra and edges with twelve OSr4CuPb octahedra. The corner-sharing octahedra tilt angles range from 0–45°. In the fourth O2- site, O2- is bonded to two equivalent Sr2+, two equivalent Tl3+, and two equivalent Pb4+ atoms to form OSr2Tl2Pb2 octahedra that share corners with twelve OSr2Tl2Pb2 octahedra and edges with twelve OSr4CuPb octahedra. The corner-sharing octahedra tilt angles range from 0–45°. In the fifth O2- site, O2- is bonded to two Sr2+, two Ca2+, and two Cu+2.12+ atoms to form distorted OSr2Ca2Cu2 octahedra that share corners with fourteen OSr4CuPb octahedra, edges with three equivalent OSr2Ca2Cu2 octahedra, and faces with six OSr4CuPb octahedra. The corner-sharing octahedra tilt angles range from 0–66°. In the sixth O2- site, O2- is bonded to two Sr2+, one Ca2+, one Nd3+, and two Cu+2.12+ atoms to form distorted OSr2CaNdCu2 octahedra that share corners with fourteen OSr4CuPb octahedra, edges with three equivalent OSr2CaNdCu2 octahedra, and faces with six OSr4CuPb octahedra.
