Zr6Pt7Ga16 crystallizes in the cubic Fm-3m space group. Zr(1) is bonded in a 12-coordinate geometry to four equivalent Pt(2), four equivalent Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded to four equivalent Zr(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of distorted corner and face-sharing PtZr4Ga8 cuboctahedra. 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 Zr(1) and three equivalent Pt(2) atoms. In the second Ga site, Ga(1) is bonded in a 4-coordinate geometry to three equivalent Zr(1), one Pt(1), and three equivalent Pt(2) atoms.
