CrPt2Ge crystallizes in the monoclinic Cm space group. Cr(1) is bonded in a 11-coordinate geometry to four equivalent Cr(1), three equivalent Pt(2), and four equivalent Ge(1) atoms. All Cr(1)-Cr(1) bond lengths are 2.83 Å. There is one shorter (3.05 Å) and two longer (3.27 Å) Cr(1)-Pt(2) bond lengths. There are a spread of Cr(1)-Ge(1) bond distances ranging from 2.70-3.17 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 8-coordinate geometry to four equivalent Pt(2) and four equivalent Ge(1) atoms. There are a spread of Pt(1)-Pt(2) bond distances ranging from 1.84-2.48 Å. There are a spread of Pt(1)-Ge(1) bond distances ranging from 2.43-2.94 Å. In the second Pt site, Pt(2) is bonded in a 8-coordinate geometry to three equivalent Cr(1), four equivalent Pt(1), and one Ge(1) atom. The Pt(2)-Ge(1) bond length is 2.58 Å. Ge(1) is bonded in a 13-coordinate geometry to four equivalent Cr(1), one Pt(2), four equivalent Pt(1), and four equivalent Ge(1) atoms. All Ge(1)-Ge(1) bond lengths are 2.83 Å.
