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.
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. All Te(1)-Te(1) bond lengths are 3.17 Å. Both Te(1)-Se(1) bond lengths are 3.08 Å. Se(1) is bonded to six equivalent Te(1) atoms to form distorted face-sharing SeTe6 pentagonal pyramids.
