The material described by Ge2Pt3 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Pt sites. In the first Pt site, Pt(4) is bonded in a 5-coordinate geometry to one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Pt site, Pt(1) is bonded in a 5-coordinate geometry to one Ge(1) and four equivalent Ge(3) atoms. In the third Pt site, Pt(2) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(3) atoms. In the fourth Pt site, Pt(3) is bonded in a 5-coordinate geometry to one Ge(2), two equivalent Ge(1), and two equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 7-coordinate geometry to one Pt(1), two equivalent Pt(4), and four equivalent Pt(3) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to one Pt(2), two equivalent Pt(3), and four equivalent Pt(4) atoms. In the third Ge site, Ge(3) is bonded in a distorted body-centered cubic geometry to two equivalent Pt(1), two equivalent Pt(2), two equivalent Pt(3), and two equivalent Pt(4) atoms. is represented by the CIF card [CIF]
