CuTe is Vulcanite structured and crystallizes in the orthorhombic Pmmn space group. The structure is two-dimensional and consists of one CuTe sheet oriented in the (0, 0, 1) direction. Cu2+ is bonded to four equivalent Te2- atoms to form a mixture of distorted corner and edge-sharing CuTe4 tetrahedra. There are two shorter (2.61 Å) and two longer (2.75 Å) Cu–Te bond lengths. Te2- is bonded in a 6-coordinate geometry to four equivalent Cu2+ atoms.
