The structure described by NpAsTe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Np(1) is bonded in a 9-coordinate geometry to four equivalent As(1) and five equivalent Te(1) atoms. As(1) is bonded in a 8-coordinate geometry to four equivalent Np(1) and four equivalent As(1) atoms. Te(1) is bonded in a 5-coordinate geometry to five equivalent Np(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
