Materials Data on Sr4Cu2Bi4O13 by Materials Project
Abstract
Sr4Cu2Bi4O13 crystallizes in the monoclinic C2 space group. The structure is two-dimensional and consists of two Sr4Cu2Bi4O13 sheets oriented in the (0, 1, 0) direction. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.52–2.90 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 2.43–3.14 Å. Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four equivalent CuO6 octahedra and a cornercorner with one BiO4 trigonal pyramid. The corner-sharing octahedra tilt angles range from 3–12°. There are a spread of Cu–O bond distances ranging from 1.96–2.67 Å. There are two inequivalent Bi+3.50+ sites. In the first Bi+3.50+ site, Bi+3.50+ is bonded to four O2- atoms to form BiO4 trigonal pyramids that share a cornercorner with one CuO6 octahedra and corners with three equivalent BiO4 trigonal pyramids. The corner-sharing octahedral tilt angles are 23°. There are a spread of Bi–O bond distances ranging from 2.11–2.20 Å. In the second Bi+3.50+ site, Bi+3.50+ ismore »
