 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).

 Title    IR Absorption of A1C1 and AlBr in Solid Noble Gases  
 Abstract    The vibrational frequency of A1 35 C1 in solid neon and argon has been measured to be 470 cm-i and 455 cm-1 . The 3 5C1/ 37 C1 isotopic splitting is 5.4 ± 0.2 cm -1 in argon matrix. The IR absorption of AlBr has been recorded in neon, argon and nitrogen matrices (370, 357, 349 cm" 1). In solid argon the frequency shift due to 81 Br/ 79 Br isotopes could be re-solved (0.95 ±0.2 cm" 1). The fundamental v3 of monomeric AlBr3 is observed at 508.4 cm -1 in an argon matrix.
