A description as a composite of CU2TeS3 and CuI is possible for (CuI)3Cu2TeS3, the first representative of a series of compounds formed by complex chalcogenometalate ions and copper(I) halides. The (TeS3)2− groups are oriented in parallel columns between layers of iodide ions (section of the crystal structure depicted on the right).
