Materials Data on NdTeF by Materials Project
NdTeF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Nd3+ is bonded in a 4-coordinate geometry to five equivalent Te2- and four equivalent F1- atoms. There are four shorter (3.22 Å) and one longer (3.38 Å) Nd–Te bond lengths. All Nd–F bond lengths are 2.60 Å. Te2- is bonded in a 9-coordinate geometry to five equivalent Nd3+ and four equivalent F1- atoms. All Te–F bond lengths are 3.47 Å. F1- is bonded to four equivalent Nd3+ and four equivalent Te2- atoms to form a mixture of edge and face-sharing FNd4Te4 tetrahedra.
