 Title    Röntgenstrukturbestimmung von A1C13-Pyridin-Addukten: Der strukturelle Aufbau im fra7is-Dichlorotetrakis(pyridin)aluminium(III)- Tetrachloroaluminat(III) und im Trichlorotris(pyridin)aluminium(III) X-ray Diffraction Study of AICI3-Pyridine Adducts: The Crystal Structure of 7ra/?s-Dichlorotetrakis(pyridine)aluminium(III)tetrachloroaluminat(III) and of Trichlorotris(pyridine)aluminium(III)  
 Abstract    Crystals of [A1(C5H5N)4C12][A1C14] are orthorhombic, Pna2lf Z = 4, a = 18.522(7), b = 15.141(5), c = 9.593(3) A, V = 2690(2) A 3 , Dc = 1.440 g/cm 3 . The structure has been solved from 5968 diffractometer measured intensities and refined by full-matrix least squares to RW(F) = 0.032. The crystal structure shows the complex to be £ra»s-dichloro-tetrakis(pyridine)aluminium(III) tetrachloroaluminat(III). The mean trans Al-Cl-and trans Al-N-distances in the octahedron are 2.279(3) and 2.070(4) A, respectively. Crystals of Al(C5H5N)3Cl3 are monoclinic, P2i/c, Z = 4, a = 7.261(2), b = 29.961(4), c = 8.624(1) A, ß = 98.12(2)°, V -1857(1) A 3 , D0 = 1.326 g/cm 3 . The structure has been solved from 4707 diffractometer measured intensities and refined to RW(F) = 0.028. The crystal structure shows octahedral complexes AICI3 • 3 (C5H5N) with trans geometry. The Al-N-distance trans to chlorine (2.096(2) A) is significantly longer than the two other Al-N-distances (mean 2.072(2) A).
