Abstract

Dy3Ru4Ga15 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 12-coordinate geometry to four Ru and twelve Ga atoms. There are two shorter (3.35 Å) and two longer (3.36 Å) Dy–Ru bond lengths. There are a spread of Dy–Ga bond distances ranging from 2.98–3.26 Å. In the second Dy site, Dy is bonded to twelve Ga atoms to form distorted face-sharing DyGa12 cuboctahedra. There are a spread of Dy–Ga bond distances ranging from 3.00–3.14 Å. In the third Dy site, Dy is bonded in a 11-coordinate geometry to eleven Ga atoms. There are a spread of Dy–Ga bond distances ranging from 3.01–3.09 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded in a 8-coordinate geometry to one Dy and eight Ga atoms. There are a spread of Ru–Ga bond distances ranging from 2.51–2.71 Å. In the second Ru site, Ru is bonded in a 9-coordinate geometry to one Dy and nine Ga atoms. There are a spread of Ru–Ga bond distances ranging from 2.54–2.79 Å. There are ten inequivalent Ga sites. In the first Ga site, Ga is bonded in a 11-coordinate geometry to three Dy, three Ru, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.75–2.90 Å. In the second Ga site, Ga is bonded in a 2-coordinate geometry to two Dy, two equivalent Ru, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.57–2.97 Å. In the third Ga site, Ga is bonded in a 2-coordinate geometry to four Dy, two Ru, and four Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.85–2.99 Å. In the fourth Ga site, Ga is bonded in a 2-coordinate geometry to three Dy, two Ru, and six Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.59–3.00 Å. In the fifth Ga site, Ga is bonded in a 2-coordinate geometry to two Dy, two equivalent Ru, and five Ga atoms. There are one shorter (2.67 Å) and two longer (2.76 Å) Ga–Ga bond lengths. In the sixth Ga site, Ga is bonded in a 4-coordinate geometry to one Dy, three Ru, and six Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.74–2.90 Å. In the seventh Ga site, Ga is bonded in a 8-coordinate geometry to two equivalent Dy, two equivalent Ru, and four Ga atoms. The Ga–Ga bond length is 2.52 Å. In the eighth Ga site, Ga is bonded in a 10-coordinate geometry to one Dy, two equivalent Ru, and seven Ga atoms. The Ga–Ga bond length is 2.67 Å. In the ninth Ga site, Ga is bonded in a 9-coordinate geometry to two Dy, two equivalent Ru, and five Ga atoms. Both Ga–Ga bond lengths are 2.79 Å. In the tenth Ga site, Ga is bonded in a 2-coordinate geometry to two equivalent Dy, two Ru, and six Ga atoms.
