USb2 crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 9-coordinate geometry to four equivalent Sb(1) and five equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded to five equivalent U(1) atoms to form a mixture of distorted edge and corner-sharing SbU5 trigonal bipyramids.
USb2 crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 9-coordinate geometry to four equivalent Sb(1) and five equivalent Sb(2) atoms. All U(1)-Sb(1) bond lengths are 3.29 Å. There are four shorter (3.15 Å) and one longer (3.24 Å) U(1)-Sb(2) bond length. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Sb(1) atoms. All Sb(1)-Sb(1) bond lengths are 3.06 Å. In the second Sb site, Sb(2) is bonded to five equivalent U(1) atoms to form a mixture of distorted edge and corner-sharing SbU5 trigonal bipyramids.
