Materials Data on UTeN by Materials Project

UNTe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one UNTe sheet oriented in the (0, 0, 1) direction. U5+ is bonded in a 4-coordinate geometry to four equivalent N3- and four equivalent Te2- atoms. All U–N bond lengths are 2.25 Å. All U–Te bond lengths are 3.22 Å. N3- is bonded to four equivalent U5+ atoms to form a mixture of edge and corner-sharing NU4 tetrahedra. Te2- is bonded in a 4-coordinate geometry to four equivalent U5+ atoms.

Materials Data on U2TeN2 by Materials Project

U2N2Te crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. U4+ is bonded in a 4-coordinate geometry to four equivalent N3- and four equivalent Te2- atoms. All U–N bond lengths are 2.25 Å. All U–Te bond lengths are 3.41 Å. N3- is bonded to four equivalent U4+ atoms to form a mixture of edge and corner-sharing NU4 tetrahedra. Te2- is bonded in a distorted body-centered cubic geometry to eight equivalent U4+ atoms.
