Title: Materials Data on Ta5GeB2 by Materials Project

Abstract

Ta5GeB2 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Ta sites. In the first Ta site, Ta is bonded to three equivalent B and two equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing TaGe2B3 trigonal bipyramids. There are two shorter (2.42 Å) and one longer (2.48 Å) Ta–B bond lengths. Both Ta–Ge bond lengths are 2.69 Å. In the second Ta site, Ta is bonded in a 4-coordinate geometry to four equivalent B and two equivalent Ge atoms. All Ta–B bond lengths are 2.50 Å. Both Ta–Ge bond lengths are 2.92 Å. B is bonded in a 9-coordinate geometry to eight Ta and one B atom. The B–B bond length is 2.15 Å. Ge is bonded in a 10-coordinate geometry to ten Ta atoms.
