The material described by Pt8Ga3Ge crystallizes in the monoclinic Pm space group. There are eight inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to one Ga(1), two equivalent Ga(2), and two equivalent Ge(1) atoms. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to two equivalent Ga(1), two equivalent Ga(3), and one Ge(1) atom. In the third Pt site, Pt(3) is bonded in a 4-coordinate geometry to one Ga(3), two equivalent Ga(2), and two equivalent Ge(1) atoms. In the fourth Pt site, Pt(4) is bonded in a 4-coordinate geometry to one Ga(2), two equivalent Ga(1), and two equivalent Ga(3) atoms. In the fifth Pt site, Pt(5) is bonded in a 3-coordinate geometry to one Ga(1), two equivalent Ga(2), and two equivalent Ga(3) atoms. In the sixth Pt site, Pt(6) is bonded in a 3-coordinate geometry to two equivalent Ga(2), two equivalent Ga(3), and one Ge(1) atom. In the seventh Pt site, Pt(7) is bonded in a 3-coordinate geometry to one Ga(3), two equivalent Ga(1), and two equivalent Ge(1) atoms. In the eighth Pt site, Pt(8) is bonded in a 3-coordinate geometry to one Ga(2), two equivalent Ga(1), and two equivalent Ge(1) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one Pt(1), one Pt(5), two equivalent Pt(2), two equivalent Pt(4), two equivalent Pt(7), and two equivalent Pt(8) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to one Pt(4), one Pt(8), two equivalent Pt(1), two equivalent Pt(3), two equivalent Pt(5), and two equivalent Pt(6) atoms. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to one Pt(3), one Pt(7), two equivalent Pt(2), two equivalent Pt(4), two equivalent Pt(5), and two equivalent Pt(6) atoms. Ge(1) is bonded in a 10-coordinate geometry to one Pt(2), one Pt(6), two equivalent Pt(1), two equivalent Pt(3), two equivalent Pt(7), and two equivalent Pt(8) atoms. is represented by the CIF card [CIF]
