    Description / Table of Contents: Syntheses and Crystal Structures of the Thiochloroantimonates(III) PPh4[Sb2SCl5] and (PPh4)2[Sb2SCl6]. CH3CN(PPh4)2Sb3Cl11, obtained from Sb2S3, PPh4Cl and HCl, reacts with Na2S4 in acetonitrile forming PPh4[Sb2SCl5]. From this and Na2S4 or from (PPh4)2[Sb2Cl8] and Na2S4 or K2S5 in acetonitrile (PPh4)2[Sb2SCl6] · CH3CN is obtained. Data obtained from the X-ray crystal structure determinations are: PPh4[Sb2SCl5], monoclinic, space group P21/c, a = 1002.9(3), b = 1705.6(5), c = 1653.7(5) pm, β = 99.12(2)°, Z = 4, R = 0.068 for 1283 reflextions; (PPh4)2[Sb2SCl6] · CH3CN, triclinic, space group P1, a = 1287.8(7), b = 1343.6(9), c = 1696.5(9) pm, α = 69.82(5), β = 85.08(4), γ = 71.54(6)°, Z = 2, R = 0.059 for 6409 reflexions. In every anion two Sb atoms are linked via one sulfur and one ore two chloro atoms, respectively. Paris of [SbSCl5]- ions are associated via Sb … S and Sb … Cl contacts forming dimer units. In both compounds every Sb atom has a distorted octahedral coordination when the lone electron pair is included in the counting.
    Notes: (PPh4)2Sb3Cl11, das aus Sb2S3, PPh4Cl und HCl erhalten wurden, reagiert mit Na2S4 in Acetonitril unter Bildung von PPh4[Sb2SCl5]. Aus diesem und Na2S4 oder aus (PPh4)2[Sb2Cl8] und Na2S4 oder K2S5 wird in Acetonitril (PPh4)2[Sb2SCl6] · CH3CN erhalten. Die Kristallstrukturbestimmungen mit Hilfe der Röntgenbeugung ergaben: PPh4[sb2SCl5], monoklin, Raumgruppe P21/c, a = 1002,9(3), b = 1705,6(5), c = 1653,7(5) pm, β = 99,12(2)°, Z = 4, R = 6,8% für 1283 Reflexe; (PPh4)2[Sb2SCl6] · CH3CN, triklin, Raumgruppe P1, a = 1287,8(7), b = 1343,6(9), c = 1696,5(9) pm, α = 69,82(5), β = 85,08(4), γ = 71,52(6)°, Z = 2, R = 5,9% für 6409 Reflexe. In den Anionen sind jeweils zwei Sb-Atome vorhanden, die über ein S- und ein bzw. zwei Cl-Atome miteinander verknüpft sind. Paare von [Sb2SCl5]- -Ionen sind über vier Sb … S und Sb … Cl-Kontakte miteinander zu einer dimeren Einheit assoziiert. In beiden Verbindungen hat ein Sb-Atom eine verzerrt oktaedrische Koordination, wenn man das einsame Elektronenpaar mitzählt.
