Materials Data on TbGa5Co by Materials Project

Abstract

TbCoGa5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Tb is bonded to twelve Ga atoms to form a mixture of face and corner-sharing TbGa12 cuboctahedra. There are four shorter (2.98 Å) and eight longer (2.99 Å) Tb–Ga bond lengths. Co is bonded in a body-centered cubic geometry to eight equivalent Ga atoms. All Co–Ga bond lengths are 2.47 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Tb, two equivalent Co, and seven Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.58–2.99 Å. In the second Ga site, Ga is bonded in a distorted square co-planar geometry to four equivalent Tb and eight equivalent Ga atoms.
