Title: Materials Data on Ba4La4Cu4(BO6)3 by Materials Project

Abstract

Ba4La4Cu4(BO6)3 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.76–3.37 Å. La3+ is bonded to seven O2- atoms to form distorted LaO7 pentagonal bipyramids that share a cornercorner with one LaO7 pentagonal bipyramid, edges with three equivalent LaO7 pentagonal bipyramids, edges with two CuO5 square pyramids, and edges with two CuO5 trigonal bipyramids. There are a spread of La–O bond distances ranging from 2.41–2.61 Å. There are four inequivalent Cu+1.75+ sites. In the first Cu+1.75+ site, Cu+1.75+ is bonded to five O2- atoms to form distorted CuO5 trigonal bipyramids that share corners with two equivalent CuO5 square pyramids, corners with two equivalent CuO5 trigonal bipyramids, and edges with four equivalent LaO7 pentagonal bipyramids.
