The crystal structure described by Te3Se crystallizes in the hexagonal P6_3/mmc space group. Te(1) is bonded in a distorted L-shaped geometry to four equivalent Te(1) and two equivalent Se(1) atoms. Se(1) is bonded to six equivalent Te(1) atoms to form distorted face-sharing SeTe6 pentagonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
