    Description / Table of Contents: The Structure of the Anion [CBr5]⊖ in Crystalline Tetraphenylphosphonium PentabromocarbonateThe structure of tetraphenylphosphonium pentabromocarbonate [(C6H5)4]⊕ [CBr5]⊖ has been determined by single-crystal X-ray diffraction. The compound crystallizes in monoclinic needless with lattice constants a = 20.19, b = 15.36, c = 8.63 Å, β = 93.20°, Z = 4, space group P21/a. The structure determination was carried out by direct methods and Fourier syntheses. The crystal contains anion bands and tetraphynylphosphonium cations. The anion bands consist of CRr4-tetrahedrons and bromide ions co-ordinated to he apices of the tetrahedrons.
    Notes: Die Struktur des Tetraphenylphosphonium-pentabromocarbonats [(C6H5)4P]⊕ [CBr5]⊖ wurde durch Röntgenbeugung am Einkristall aufgeklärt. Die Verbindung kristallisiert in monoklinen Nadeln mit den Gitterkonstanten a = 20.19, b = 15.36, c = 8.63 Å, β = 93.20, Z = 4, Raumgruppe P21/a. Die Strukturaufklärung erfolgte durch direkte Methoden und Fourier-Synthesen. Der Kristall ist aus polymeren Anionenbändern und Tetraphenylphosphonium-Kationen aufgebaut. Die Anionenbänder sind aus CBr4-Tetraedern und über Tetraederspitzen koordinierten Bromid-Ionen zusammengesetzt.
