The structure described by UH3 crystallizes in the tetragonal P4_2/mmc space group. U(1) is bonded to four equivalent H(2) and eight equivalent H(1) atoms to form a mixture of edge and face-sharing UH12 cuboctahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded to four equivalent U(1) atoms to form a mixture of distorted corner and edge-sharing HU4 tetrahedra. In the second H site, H(2) is bonded to four equivalent U(1) atoms to form a mixture of distorted corner and edge-sharing HU4 tetrahedra. is represented by the CIF card [CIF]
