The crystal structure described by 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. is represented by the CIF file [CIF]
