    Notes: (CuI)2Cu3SbS3 was prepared by solid-state reaction of stoichiometric amounts of CuI, Cu, S, and Sb. The crystal structure was determined from single crystals at room temperature and - 80°C. Red-orange (CuI)2Cu3SbS3 crystallizes in the orthorhombic system, space group Pnnm (no. 58) with a = 10.488(2), b = 12.619(2), c = 7.316(1) Å, V = 968.2(2) Å3 (20°C), and Z = 4. The distribution of the copper atoms was refined by using a Gram-Charlier nonharmonic development of their atomic displacement parameters, which indicated an increasing dynamic disorder from -80°C to 20°C. Raman spectra of (CuI)2Cu3SbS3 are dominated by strong bands for [SbS3]3- units at 362 and 338 cm-1. The compound melts at 492°C (DTA, onset). Conductivity measurements reveal high ionic conductivity (6.2 × 10-5ω-1 cm-1 at 50°C, 2.9 × 10-3 ω-1 cm-1 at 200°C) with an activation energy of 0.35 eV (40-275°C).

    Cu3SbSe3: Synthese und Kristallstruktur (1995)
    Weinheim : Wiley-Blackwell

    Description / Table of Contents: The Crystal Structure of Cu3SbSe3The hitherto unknown crystal structure of Cu3SbSe3 has been determined from single crystals. The compound crystallizes in the orthorhombic system, space group Pnma (No. 62), with a = 7.9865(8), b = 10.6138(9) and c = 6.8372(7) Å, V = 579.6(1) Å3, Z = 4. Most remarkable feature of the structure are groups of three cis-edge-sharing tetrahedra [Cu3Se8] which are interlinked to a threedimensional arrangement by SbSe3-units. In contrast to Cu3SbS3 in the temperature range from -180 to 25°C no hints for a phase transition could be detected by means of X-ray- and thermoanalytical methods.
    Notes: Die bisher unbekannte Kristallstruktur von Cu3SbSe3 wurde aus Einkristalldaten ermittelt. Die Verbindung kristallisiert orthorhombisch, RG Pnma (Nr. 62) mit a = 7,9865(8), b = 10,6138(9) und c = 6,8372(7) Å, V = 579.6(1) Å3, Z = 4. Die Struktur zeichnet sich durch Baugruppen [Cu3Se8] aus drei cis-kantenverknüpften Tetraedern aus, die über ihre Liganden mit SbSe3-Gruppen zu einem dreidimensionalen Netzwerk verknüpft sind. Im Gegensatz zu Cu3SbS3 konnten Hinweise auf eine Phasenumwandlung im Temperaturbereich von -180 bis 25°C weder durch röntgenographische noch durch thermoanalytische Untersuchungen gefunden werden.
