description: Yb4Ni10Ga21 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Yb sites. In the first Yb site, Yb is bonded in a 2-coordinate geometry to four Ni and eleven Ga atoms. There are two shorter (3.03 Å) and two longer (3.09 Å) Yb–Ni bond lengths. There are a spread of Yb–Ga bond distances ranging from 2.87–3.42 Å. In the second Yb site, Yb is bonded in a 7-coordinate geometry to four Ni and ten Ga atoms. There are two shorter (3.06 Å) and two longer (3.16 Å) Yb–Ni bond lengths. There are a spread of Yb–Ga bond distances ranging from 2.88–3.18 Å. There are five inequivalent Ni sites. In the first Ni site, Ni is bonded in a 10-coordinate geometry to two equivalent Yb, one Ni, and seven Ga atoms. The Ni–Ni bond length is 2.74 Å. There are a spread of Ni–Ga bond distances ranging from 2.46–2.56 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to nine Ga atoms. There are a spread of Ni–Ga bond distances ranging from 2.48–2.62 Å. In the third Ni site, Ni is bonded in a 10-coordinate geometry to two equivalent Yb, one Ni, and seven Ga atoms.
