CuTe2C1 is monoclinic, space group P21/c, with a=8.207, b=4.935, c= 15.279 A, fl= 134-92 °, Z=4.722 independent intensities were measured and the structure was refined to R = 5.6 %. The basic structure unit is a pseudo-fourfold screw of Te atoms along b. The Te-Te distances in the screw are 2-737 and 2.792 A. Cu-C1-Cu links connect the screws to layers in the ab plane. The coordination of the Cu atom by Te and C1 is fourfold with the geometry of a slightly distorted tetrahedron.
