The compound described by Pt3Ge crystallizes in the monoclinic C2/m space group. There are three inequivalent Pt sites. In the first Pt site, Pt(3) is bonded in a distorted water-like geometry to four equivalent Pt(1) and two equivalent Ge(1) atoms. In the second Pt site, Pt(1) is bonded to four equivalent Pt(2), four equivalent Pt(3), and four equivalent Ge(1) atoms to form a mixture of distorted corner and face-sharing PtGe4Pt8 cuboctahedra. In the third Pt site, Pt(2) is bonded in a distorted water-like geometry to four equivalent Pt(1) and two equivalent Ge(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to two equivalent Pt(2), two equivalent Pt(3), and four equivalent Pt(1) atoms. is represented by the CIF file [CIF]
