Materials Data on CrRe3B4 by Materials Project
CrRe3B4 is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. Cr3+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of Cr–B bond distances ranging from 2.19–2.54 Å. There are three inequivalent Re3+ sites. In the first Re3+ site, Re3+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of Re–B bond distances ranging from 2.25–2.74 Å. In the second Re3+ site, Re3+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of Re–B bond distances ranging from 2.26–2.37 Å. In the third Re3+ site, Re3+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of Re–B bond distances ranging from 2.25–2.75 Å. There are four inequivalent B3- sites. In the first B3- site, B3- is bonded in a 9-coordinate geometry to one Cr3+, six Re3+, and two equivalent B3- atoms. Both B–B bond lengths are 1.86 Å. In the second B3- site, B3- is bonded in a 9-coordinate geometry to seven Re3+ and two equivalent B3- atoms. In the third B3- site, B3- is bonded in a 9-coordinate geometry to four equivalent Cr3+, three Re3+, and two equivalent B3- atoms. Both B–B bond lengths are 1.82 Å. In the fourth B3- site, B3- is bonded in a 9-coordinate geometry to two equivalent Cr3+, five Re3+, and two equivalent B3- atoms.
