    Description / Table of Contents: S4N3⊕[ReCl4(NSCl)2]⊖. Synthesis and Crystal StructureS4N3⊕[ReCl4(NSCl)2]⊖ is formed as a byproduct in the reaction of Re2(CO)10 with excess trithiazyl chloride. The compound is characterized by a crystal structure analysis by X-ray methods. S4N3[ReCl4(NSCl)2] crystallizes in the noncentrosymmetric space group P212121 with four formula units per unit cell and the lattice dimensions a = 980, b = 1205, c = 1362 pm (2376 observed, independent reflexions; R = 0.076). The compound consists of the well known cyclic planar S4N3⊕-cations and anions [ReCl4(NSCl)2]⊖, in which the rhenium atom is coordinated octahedral by four Cl atoms and two cis-positioned NSCl ligands. The mean Re—N and N—S bond lengths (177 pm and 158 pm) correspond to double bonds. The bond lengths and angles are much like in the structure of AsPh4[ReCl4(NSCl)2]; however the chlorine atoms of the NSCl ligands are turned to each other.
    Notes: S4N3⊕[ReCl4(NSCl)2]⊖ entsteht als Nebenprodukt bei der Umsetzung von Re2(CO)10 mit überschüssigem Trithiazylchlorid. Die Verbindung wird durch eine röntgenographische Kristallstrukturanalyse charakterisiert. S4N3[ReCl4(NSCl)2] kristallisiert in der azentrischen Raumgruppe P212121 mit vier Formeleinheiten pro Elementarzelle und den Gitterabmessungen a = 980, b = 1205, c = 1362 pm (2376 unabhängige, beobachtete Reflexe, R = 7,6%). Die Verbindung besteht aus den bekannten ebenen, cyclischen S4N3⊕-Kationen und Anionen [ReCl4(NSCl)2]⊖, in denen das Rheniumatom oktaedrisch von vier Chloratomen und von den N-Atomen der cis-ständigen NSCl-Liganden umgeben ist. Die Re—N- und die N—S-Abstände entsprechen im Mittel mit 177 bzw. 158 pm etwa Doppelbindungen. Die Bindungsabstände und -winkel entsprechen der Struktur des AsPh4[ReCl4(NSCl)2], jedoch sind die Chloratome einander zugewandt.

    Description / Table of Contents: On 121Sb-Mössbauer Effect. VIII. Vibrational Spectrum and 121Sb-Mössbauer Spectrum of P2O3Cl4 · 2 SbCl5. Crystal Structure of [SbCl4(O2PCl2)]2The donor-acceptor complex P2O3Cl4 · 2 SbCl5 is prepared from P2O3Cl4 and excess SbCl5 in carbon tetrachloride at -20°C. According to the vibrational spectrum and the 121Sb-Mössbauer parameters the SbCl5 molecules are bonded to the terminal O atoms of P2O3Cl4. Thermolysis of the adduct yields the dichloro phosphate [SbCl4(O2PCl2)]2 which has been discussed earlier. The crystal structure of the dimer was determined by means of X-ray diffraction; it crystallizes monoclinic in the space group P21/c with two dimeric molecules per unit cell (1843 independent, observed reflexions, R = 4.0%). The cell dimensions are a = 857 pm, b = 1144 pm, c = 1091 pm; β = 108.6°. In the molecule two SbCl4 units are linked by the O atoms of the dichlorophosphate groups to form a centrosymmetric eightmembered ring with chair conformation.
    Notes: Der Donor-Akzeptorkomplex P2O3Cl4 · 2 SbCl5 wird bei -20°C aus P2O3Cl4 und überschüssigem SbCl5 in Tetrachlorkohlenstoff hergestellt. Nach dem Schwingungsspektrum und nach den 121Sb-Mößbauer-Parametern sind die SbCl5-Moleküle an die terminalen O-Atome des P2O3Cl4 gebunden. Thermolyse des Addukts führt zu dem bereits früher beschriebenen Dichlorphosphat [SbCl4(O2PCl2)]2, dessen Kristallstruktur mit Hilfe von Röntgenbeugung ermittelt wurde. Die Verbindung kristallisiert monoklin in der Raumgruppe P21/c mit zwei dimeren Molekülen pro Elementarzelle (1843 unabhängige, beobachtete Reflexe, R = 4,0%). Die Gitterabmessungen sind a = 857, b = 1144, c = 1091 pm; β = 108,6°. In dem Molekül sind zwei SbCl4-Einheiten über die O-Atome der Dichlorophosphatgruppen zu einem zentrosymmetrischen Sb2O4P2-Achtring der Sesselkonformation verknüpft.
