资源简介：
NbWB2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Nb4+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of Nb–B bond distances ranging from 2.39–2.54 Å. W2+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are six shorter (2.37 Å) and one longer (2.60 Å) W–B bond lengths. There are two inequivalent B3- sites. In the first B3- site, B3- is bonded in a 9-coordinate geometry to three equivalent Nb4+, four equivalent W2+, and two equivalent B3- atoms. Both B–B bond lengths are 1.87 Å. In the second B3- site, B3- is bonded in a 9-coordinate geometry to four equivalent Nb4+, three equivalent W2+, and two equivalent B3- atoms.
