UPt2 crystallizes in the orthorhombic Cmcm space group. U(1) is bonded in a 9-coordinate geometry to five equivalent Pt(2) and six equivalent Pt(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to six equivalent U(1), two equivalent Pt(1), and four equivalent Pt(2) atoms to form a mixture of distorted edge, face, and corner-sharing PtU6Pt6 cuboctahedra. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to five equivalent U(1) and four equivalent Pt(1) atoms.
UPt2 crystallizes in the orthorhombic Cmcm space group. U(1) is bonded in a 9-coordinate geometry to five equivalent Pt(2) and six equivalent Pt(1) atoms. There are a spread of U(1)-Pt(2) bond distances ranging from 2.85-3.04 Å. There are four shorter (3.07 Å) and two longer (3.54 Å) U(1)-Pt(1) bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to six equivalent U(1), two equivalent Pt(1), and four equivalent Pt(2) atoms to form a mixture of distorted edge, face, and corner-sharing PtU6Pt6 cuboctahedra. Both Pt(1)-Pt(1) bond lengths are 2.86 Å. All Pt(1)-Pt(2) bond lengths are 2.83 Å. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to five equivalent U(1) and four equivalent Pt(1) atoms.
