Materials Data on Ti6Ga16Ru7 by Materials Project

Ti6Ru7Ga16 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ti is bonded in a 12-coordinate geometry to four equivalent Ru and eight Ga atoms. All Ti–Ru bond lengths are 3.08 Å. There are four shorter (2.72 Å) and four longer (2.84 Å) Ti–Ga bond lengths. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded to four equivalent Ti and eight Ga atoms to form a mixture of distorted face and corner-sharing RuTi4Ga8 cuboctahedra. There are four shorter (2.53 Å) and four longer (2.67 Å) Ru–Ga bond lengths. In the second Ru site, Ru is bonded in a body-centered cubic geometry to eight equivalent Ga atoms. All Ru–Ga bond lengths are 2.61 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 6-coordinate geometry to three equivalent Ti and three equivalent Ru atoms. In the second Ga site, Ga is bonded in a 4-coordinate geometry to three equivalent Ti and four Ru atoms.
