Nb2Pt is beta Uranium-derived structured and crystallizes in the tetragonal P4_2/mnm space group. There are three inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 15-coordinate geometry to one Nb(1), two equivalent Nb(2), six equivalent Nb(3), two equivalent Pt(1), and four equivalent Pt(2) atoms. In the second Nb site, Nb(2) is bonded in a 4-coordinate geometry to one Nb(1) and four equivalent Pt(2) atoms. In the third Nb site, Nb(3) is bonded in a 7-coordinate geometry to two equivalent Nb(3), three equivalent Nb(1), one Pt(1), and four equivalent Pt(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to four equivalent Nb(1), four equivalent Nb(3), and four equivalent Pt(2) atoms to form PtNb8Pt4 cuboctahedra that share corners with sixteen equivalent Pt(2)Nb10Pt2 cuboctahedra, edges with two equivalent Pt(1)Nb8Pt4 cuboctahedra, and faces with four equivalent Pt(2)Nb10Pt2 cuboctahedra. In the second Pt site, Pt(2) is bonded to two equivalent Nb(1), four equivalent Nb(2), four equivalent Nb(3), one Pt(1), and one Pt(2) atom to form distorted PtNb10Pt2 cuboctahedra that share corners with four equivalent Pt(1)Nb8Pt4 cuboctahedra, corners with seven equivalent Pt(2)Nb10Pt2 cuboctahedra, edges with three equivalent Pt(2)Nb10Pt2 cuboctahedra,  a faceface with one Pt(1)Nb8Pt4 cuboctahedra, and faces with six equivalent Pt(2)Nb10Pt2 cuboctahedra.
