Materials Data on Ni(BW)2 by Materials Project

Ni(WB)2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. W2+ is bonded in a 6-coordinate geometry to six equivalent B3- atoms. There are four shorter (2.33 Å) and two longer (2.54 Å) W–B bond lengths. Ni2+ is bonded in a square co-planar geometry to four equivalent B3- atoms. All Ni–B bond lengths are 2.10 Å. B3- is bonded in a 9-coordinate geometry to six equivalent W2+, two equivalent Ni2+, and one B3- atom. The B–B bond length is 1.86 Å.

Materials Data on Ni(BW)3 by Materials Project

Ni(WB)3 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 6-coordinate geometry to six B3- atoms. There are a spread of W–B bond distances ranging from 2.31–2.54 Å. In the second 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 2.36–2.48 Å. Ni2+ is bonded in a square co-planar geometry to four equivalent B3- atoms. All Ni–B bond lengths are 2.10 Å. There are two inequivalent B3- sites. In the first B3- site, B3- is bonded in a 9-coordinate geometry to six W+2.33+, two equivalent Ni2+, and one B3- atom. The B–B bond length is 1.87 Å. In the second B3- site, B3- is bonded in a 9-coordinate geometry to seven W+2.33+ and two equivalent B3- atoms.
