PtSiSb2 crystallizes in the monoclinic Cm space group. Pt(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. There are a spread of Pt(1)-Sb(1) bond distances ranging from 2.63-3.18 Å. Si(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. There are two shorter (2.63 Å) and two longer (2.86 Å) Si(1)-Sb(1) bond lengths. Sb(1) is bonded in a 5-coordinate geometry to three equivalent Pt(1) and two equivalent Si(1) atoms.
