The compound described by Ti6Pt7Ga16 crystallizes in the cubic Fm-3m space group. Ti(1) is bonded in a distorted square co-planar geometry to four equivalent Ga(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a 8-coordinate geometry to four equivalent Ga(1) and four equivalent Ga(2) atoms. In the second Pt site, Pt(1) is bonded in a body-centered cubic geometry to eight equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(2) is bonded in a 6-coordinate geometry to three equivalent Ti(1) and three equivalent Pt(2) atoms. In the second Ga site, Ga(1) is bonded to one Pt(1) and three equivalent Pt(2) atoms to form a mixture of distorted corner and edge-sharing GaPt4 tetrahedra. is represented by the CIF file [CIF]
