GeTe crystallizes in the orthorhombic Pbcn space group. The structure is one-dimensional and consists of four GeTe ribbons oriented in the (1, 0, 0) direction. Ge2+ is bonded in a 4-coordinate geometry to three equivalent Te2- atoms. There are two shorter (2.78 Å) and one longer (2.86 Å) Ge–Te bond lengths. Te2- is bonded in a 3-coordinate geometry to three equivalent Ge2+ atoms.
