The material described by Pt3Si is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 3-coordinate geometry to three equivalent Si(1) atoms. In the second Pt site, Pt(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Si(1) atoms. Si(1) is bonded in a 8-coordinate geometry to two equivalent Pt(2) and six equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
