Materials Data on Cr5B3 by Materials Project
Cr5B3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Cr sites. In the first Cr site, Cr is bonded in a 5-coordinate geometry to five B atoms. There are a spread of Cr–B bond distances ranging from 2.16–2.27 Å. In the second Cr site, Cr is bonded in a 6-coordinate geometry to six B atoms. There are four shorter (2.18 Å) and two longer (2.49 Å) Cr–B bond lengths. There are two inequivalent B sites. In the first B site, B is bonded in a 10-coordinate geometry to ten Cr atoms. In the second B site, B is bonded in a 9-coordinate geometry to eight Cr and one B atom. The B–B bond length is 1.81 Å.
