Materials Data on Sr10Ca4Cu10Bi11O40 by Materials Project
Abstract
Sr10Ca4Cu10Bi11O40 crystallizes in the tetragonal I4/m space group. The structure is two-dimensional and consists of two Sr10Ca4Cu10Bi11O40 sheets oriented in the (0, 0, 1) direction. there are two 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 2.64–2.77 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 2.61–2.81 Å. Ca2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.45–2.49 Å. There are two inequivalent Cu+1.90+ sites. In the first Cu+1.90+ site, Cu+1.90+ is bonded to five O2- atoms to form distorted CuO5 square pyramids that share a cornercorner with one BiO5 square pyramid and corners with four equivalent CuO5 square pyramids. There are four shorter (1.87 Å) and one longer (2.59 Å) Cu–O bond lengths. In the second Cu+1.90+ site, Cu+1.90+ is bonded to five O2- atoms to form distorted CuO5 square pyramids that share a cornercorner with one BiO5 square pyramid and corners with four CuO5 square pyramids.more »
