The crystal structure described by Pt2W is alpha Samarium-derived structured and crystallizes in the orthorhombic Immm space group. W(1) is bonded to two equivalent W(1) and ten equivalent Pt(1) atoms to form WPt10W2 cuboctahedra that share corners with two equivalent W(1)Pt10W2 cuboctahedra, corners with ten equivalent Pt(1)Pt7W5 cuboctahedra, edges with twelve equivalent W(1)Pt10W2 cuboctahedra, edges with twelve equivalent Pt(1)Pt7W5 cuboctahedra, faces with four equivalent W(1)Pt10W2 cuboctahedra, and faces with fourteen equivalent Pt(1)Pt7W5 cuboctahedra. Pt(1) is bonded to five equivalent W(1) and seven equivalent Pt(1) atoms to form PtPt7W5 cuboctahedra that share corners with five equivalent W(1)Pt10W2 cuboctahedra, corners with seven equivalent Pt(1)Pt7W5 cuboctahedra, edges with six equivalent W(1)Pt10W2 cuboctahedra, edges with eighteen equivalent Pt(1)Pt7W5 cuboctahedra, faces with seven equivalent W(1)Pt10W2 cuboctahedra, and faces with eleven equivalent Pt(1)Pt7W5 cuboctahedra. is represented by the CIF card [CIF]
