CuClSe1.53Te0.47 and CuClSe0.56Te1.44 are obtained from the reaction of CuCl, Se, and Te in stoichiometric amounts. Both copper(l) selenium tellurium chlorides are monoclinic, space group P2(1)/n (no. 14) with lattice constants of a = 7.837(1) A, b = 4.699(1) Angstrom, c = 10.762(2) Angstrom, beta = 104.37(2)degrees, V = 383.9(1) Angstrom(3) (CuClSe0.56Te1.44), and Z = 4. A common feature of these isostructural compounds are heteroatomic strands (1)(infinity)[YY'] (Y, Y' = chalcogen). These strands are running along [010] and are connected to layers by chains (1)(infinity)[CuCl]. Vibrational spectra of CuClSe1.53Te0.47, CuClSe0.56Te1.44, CuXTe2 and CuX'Se-2 (X = Cl, Br, I; X' = Cl, Br) are analysed with respect to the bonding relations of the chalcogen chains. Modes derived from IR and Raman spectra are assigned by correlation with trigonal Se and related copper(I) chalcogen halides. Both, X-ray structural data and an analysis of the chalcogen vibrational modes in IR and Raman spectra, lead to a detailed insight into the ordering phenomena of the chalcogen chains in this type of copper(I) chalcogen halides.
