Materials Data on Ta(BMo)2 by Materials Project

Ta(MoB)2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Ta is bonded to eight equivalent Mo and four equivalent B atoms to form a mixture of distorted corner and face-sharing TaB4Mo8 cuboctahedra. All Ta–Mo bond lengths are 2.77 Å. All Ta–B bond lengths are 2.49 Å. Mo is bonded in a 10-coordinate geometry to four equivalent Ta and six equivalent B atoms. There are four shorter (2.39 Å) and two longer (2.47 Å) Mo–B bond lengths. B is bonded in a 9-coordinate geometry to two equivalent Ta, six equivalent Mo, and one B atom. The B–B bond length is 1.89 Å.
