Pt2Mo crystallizes in the orthorhombic Immm space group. Mo(1) is bonded to two equivalent Mo(1) and ten equivalent Pt(1) atoms to form MoMo2Pt10 cuboctahedra that share corners with two equivalent Mo(1)Mo2Pt10 cuboctahedra, corners with ten equivalent Pt(1)Mo5Pt7 cuboctahedra, edges with twelve equivalent Mo(1)Mo2Pt10 cuboctahedra, edges with twelve equivalent Pt(1)Mo5Pt7 cuboctahedra, faces with four equivalent Mo(1)Mo2Pt10 cuboctahedra, and faces with fourteen equivalent Pt(1)Mo5Pt7 cuboctahedra. Pt(1) is bonded to five equivalent Mo(1) and seven equivalent Pt(1) atoms to form PtMo5Pt7 cuboctahedra that share corners with five equivalent Mo(1)Mo2Pt10 cuboctahedra, corners with seven equivalent Pt(1)Mo5Pt7 cuboctahedra, edges with six equivalent Mo(1)Mo2Pt10 cuboctahedra, edges with eighteen equivalent Pt(1)Mo5Pt7 cuboctahedra, faces with seven equivalent Mo(1)Mo2Pt10 cuboctahedra, and faces with eleven equivalent Pt(1)Mo5Pt7 cuboctahedra.

Both Mo(1)-Mo(1) bond lengths are 2.76 Å. There are eight shorter (2.77 Å) and two longer (2.80 Å) Mo(1)-Pt(1) bond lengths. Pt(1) is bonded to five equivalent Mo(1) and seven equivalent Pt(1) atoms to form PtMo5Pt7 cuboctahedra that share corners with five equivalent Mo(1)Mo2Pt10 cuboctahedra, corners with seven equivalent Pt(1)Mo5Pt7 cuboctahedra, edges with six equivalent Mo(1)Mo2Pt10 cuboctahedra, edges with eighteen equivalent Pt(1)Mo5Pt7 cuboctahedra, faces with seven equivalent Mo(1)Mo2Pt10 cuboctahedra, and faces with eleven equivalent Pt(1)Mo5Pt7 cuboctahedra. There are a spread of Pt(1)-Pt(1) bond distances ranging from 2.72-2.81 Å.
