    Description / Table of Contents: On Formation and Structure of Calcium ChlorosulfateCa(SO3Cl)2 crystals are formed in sealed pyrex-ampouls as a result of an unexpected side-reaction in the system H2SO4/CaSO4/SOCl2. The up to day not described compound crystallizes in the orthorhombic space group Pbca with lattice constants a = 9.182(2), b = 17.269(3) and c = 10.250(2) Å. The volume of the unit cell has been determined to V = 2160 Å3 and the number of formula units to Z = 8(Dcalc. = 2.160 g/cm3).There are two crystallographically independent, distorted tetrahedral SO3Cl anions. The structure is characterized by isolated, less distorted CaO6 octahedra which are linked to a three dimensional lattice structure over in each case 6 SO3Cl tetrahedra.
    Notes: Im System H2SO4/CaSO4/SOCl2 bilden sich in abgeschmolzenen Glasampullen im Ergebnis einer nicht beabsichtigten Nebenreaktion Calciumchlorosulfat-Einkristalle aus. Die bisher nicht beschriebene, hydrolyseempfindliche Verbindung kristallisiert in der orthorhombischen Raumgruppe Pbca mit dem Gitterkonstanten a = 9,182(2), b = 17,269(3) und c = 10,250(2) Å. Das Volumen der Elementarzelle wurde zu V = 2160 Å3 und die Zahl der Formeleinheiten zu Z = 8 bestimmt (Dber = 2,160 g/cm3).Es liegen zwei kristallographisch unabhängige, verzerrt tetraedrische SO3Cl-Anionen vor. Die Struktur ist charakterisiert durch isolierte, leicht verzerrte CaO6-Oktaeder, die über jeweils 6 SO3Cl-Tetraeder miteinander zu einer dreidimensionalen Gitterstruktur verbunden sind.
