Materials Data on Ba5Re3ClO15 by Materials Project

Abstract

Ba5(ReO5)3Cl crystallizes in the hexagonal P6_3cm space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to nine O2- and two equivalent Cl1- atoms. There are a spread of Ba–O bond distances ranging from 2.79–3.28 Å. There are one shorter (3.40 Å) and one longer (3.71 Å) Ba–Cl bond lengths. In the second Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.76–2.82 Å. Re7+ is bonded in a distorted trigonal bipyramidal geometry to five O2- atoms. There are a spread of Re–O bond distances ranging from 1.76–1.87 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Ba2+ and one Re7+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one Re7+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to three equivalent Ba2+, one Re7+, and one Cl1- atom. The O–Cl bond length is 3.53 Å. Cl1- is bonded in a 6-coordinate geometry to six equivalent Ba2+ and three equivalent O2- atoms.
