Abstract

W3CoB3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent W+2.33+ sites. In the first W+2.33+ site, W+2.33+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of W–B bond distances ranging from 2.36–2.49 Å. In the second W+2.33+ site, W+2.33+ is bonded in a 6-coordinate geometry to six B3- atoms. There are a spread of W–B bond distances ranging from 2.32–2.52 Å. Co2+ is bonded in a square co-planar geometry to four equivalent B3- atoms. All Co–B bond lengths are 2.07 Å. There are two inequivalent B3- sites. In the first B3- site, B3- is bonded in a 9-coordinate geometry to seven W+2.33+ and two equivalent B3- atoms. Both B–B bond lengths are 1.90 Å. In the second B3- site, B3- is bonded in a 9-coordinate geometry to six W+2.33+, two equivalent Co2+, and one B3- atom.
