The material structure described by Pt3Ga crystallizes in the orthorhombic Fmmm space group. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted water-like geometry to four equivalent Pt(2) and four equivalent Ga(1) atoms. In the second Pt site, Pt(2) is bonded to eight Pt(1,1) and four equivalent Ga(1) atoms to form distorted PtGa4Pt8 cuboctahedra that share corners with twelve equivalent Pt(2)Ga4Pt8 cuboctahedra, edges with eight equivalent Ga(1)Pt12 cuboctahedra, faces with four equivalent Ga(1)Pt12 cuboctahedra, and faces with six equivalent Pt(2)Ga4Pt8 cuboctahedra. In the third Pt site, Pt(1) is bonded in a distorted water-like geometry to four equivalent Pt(2) and four equivalent Ga(1) atoms. Ga(1) is bonded to four equivalent Pt(2) and eight Pt(1,1) atoms to form distorted GaPt12 cuboctahedra that share corners with twelve equivalent Ga(1)Pt12 cuboctahedra, edges with eight equivalent Pt(2)Ga4Pt8 cuboctahedra, faces with four equivalent Pt(2)Ga4Pt8 cuboctahedra, and faces with six equivalent Ga(1)Pt12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
