The compound described by Bi2Pt is Marcasite-like structured and crystallizes in the orthorhombic Pbca space group. Pt(1) is bonded to three equivalent Bi(1) and three equivalent Bi(2) atoms to form a mixture of corner and edge-sharing PtBi6 octahedra. The corner-sharing octahedral tilt angles range from 52-64°. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 4-coordinate geometry to three equivalent Pt(1) and one Bi(2) atom. In the second Bi site, Bi(2) is bonded in a 4-coordinate geometry to three equivalent Pt(1) and one Bi(1) atom. is represented by the CIF card [CIF]
