description: Tb4Ni10Ga21 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 2-coordinate geometry to four Ni and eleven Ga atoms. There are two shorter (3.03 Å) and two longer (3.14 Å) Tb–Ni bond lengths. There are a spread of Tb–Ga bond distances ranging from 2.87–3.41 Å. In the second Tb site, Tb is bonded in a 7-coordinate geometry to four Ni and ten Ga atoms. There are two shorter (3.06 Å) and two longer (3.18 Å) Tb–Ni bond lengths. There are a spread of Tb–Ga bond distances ranging from 2.89–3.21 Å. There are five inequivalent Ni sites. In the first Ni site, Ni is bonded in a 10-coordinate geometry to two equivalent Tb, one Ni, and seven Ga atoms. The Ni–Ni bond length is 2.76 Å.
