UPSe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 9-coordinate geometry to four equivalent P(1) and five equivalent Se(1) atoms. P(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent P(1) atoms. Se(1) is bonded in a 5-coordinate geometry to five equivalent U(1) atoms.
UPSe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 9-coordinate geometry to four equivalent P(1) and five equivalent Se(1) atoms. All U(1)-P(1) bond lengths are 2.93 Å. There are four shorter (2.93 Å) and one longer (3.22 Å) U(1)-Se(1) bond length. P(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent P(1) atoms. All P(1)-P(1) bond lengths are 2.75 Å. Se(1) is bonded in a 5-coordinate geometry to five equivalent U(1) atoms.
