    Description / Table of Contents: CuClS0.94Te1.06 and CuBrS0.92Te1.08, Two New Copper(I) Chalcogen Halides Containing Neutral ∞1[STe] ScrewsCuClS0.94Te1.06 and CuBrS0.92Te1.08 are two new, isotypic compounds of general composition CuXYY′ (X = halide, Y, Y′ = chalcogen) with a mixed chalcogen substructure. They crystallize in the monoclinic system, space group P21/n (No. 14), a = 7.878(2), b = 4.727(1), c = 10.759(2) Å, β = 103.97(2)°, V = 388.8(2) Å3 (CuClS0.94Te1.06) and a = 8.043(3), b = 4.746(2), c = 11.240(4) Å, β = 103.46(3)°, V = 417.3(3) Å3 (CuBrS0.92Te1.08), both with Z = 4. The crystal structures are dominated by ordered ∞1[STe±0]-screws. From a crystal chemical point of view the sulfur and tellurium atoms are significantly different. The melting points are 341 °C (CuClS0.94Te1.06) and 336 °C (CuBrS0.92Te1.08). The compounds CuXYY′ (X = Cl, Br, I; Y, Y′ = S, Se, Te) are compared and discussed.
    Notes: Mit CuClS0.94Te1.06 und CuBrS0.92Te1.08 wurden zwei neue, isotype Verbindungen der Zusammensetzung CuXYY′ (X = Halogenid, Y, Y′ = Chalkogen) mit gemischtem Chalkogenteilgitter erhalten. Sie kristallisieren monoklin, RG P21/n (Nr. 14) mit a = 7,878(2), b = 4,727(1) und c = 10,759(2) Å, β = 103,97(2)°, V = 388,8(2) Å3 (CuClS0.94Te1.06) bzw. a = 8,043(3), b = 4,746(2) und c = 11,240(4) Å, β = 103,46(3)°, V = 417,3(3) Å3 (CuBrS0.92Te1.08), jeweils mit Z = 4. Strukturbestimmendes Merkmal sind die geordneten ∞1[STe±0]-Schrauben. Kristallchemisch sind die Schwefel- und Telluratome deutlich unterschiedlich. Die Schmelzpunkte liegen bei 341 °C (CuClS0.94Te1.06) bzw. 336 °C (CuBrS0.92Te1.08). Die Strukturen von CuXYY′ (X = Cl, Br, I; Y, Y′ = S, Se, Te) werden verglichen und diskutiert.
