The compound described by HoPtGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 14-coordinate geometry to four equivalent Pt(1), two equivalent Ge(1), four equivalent Ge(2), and four equivalent Ge(3) atoms. In the second Ho site, Ho(2) is bonded in a 14-coordinate geometry to six equivalent Pt(1), two equivalent Ge(3), and six equivalent Ge(1) atoms. Pt(1) is bonded in a 10-coordinate geometry to two equivalent Ho(1), three equivalent Ho(2), one Ge(2), one Ge(3), and three equivalent Ge(1) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to one Ho(1), three equivalent Ho(2), three equivalent Pt(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to four equivalent Ho(1), two equivalent Pt(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), two equivalent Pt(1), and one Ge(3) atom. is represented by the CIF file [CIF]
