Dy2Te5 crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two Dy2Te5 sheets oriented in the (0, 1, 0) direction. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 9-coordinate geometry to nine Te+1.20- atoms. There are a spread of Dy–Te bond distances ranging from 3.24–3.31 Å. In the second Dy3+ site, Dy3+ is bonded in a 9-coordinate geometry to nine Te+1.20- atoms. There are a spread of Dy–Te bond distances ranging from 3.19–3.33 Å. There are five inequivalent Te+1.20- sites. In the first Te+1.20- site, Te+1.20- is bonded in a 6-coordinate geometry to two equivalent Dy3+ and four equivalent Te+1.20- atoms. All Te–Te bond lengths are 3.09 Å. In the second Te+1.20- site, Te+1.20- is bonded in a 6-coordinate geometry to two equivalent Dy3+ and four equivalent Te+1.20- atoms. In the third Te+1.20- site, Te+1.20- is bonded in a 8-coordinate geometry to four equivalent Dy3+ and four equivalent Te+1.20- atoms. All Te–Te bond lengths are 3.09 Å. In the fourth Te+1.20- site, Te+1.20- is bonded in a 5-coordinate geometry to five Dy3+ atoms. In the fifth Te+1.20- site, Te+1.20- is bonded in a 5-coordinate geometry to five Dy3+ atoms.
