N2 - A number of adducts of aluminium(III) chloride with unidentate nitrogen bases have been synthesized and their room-temperature single-crystal structures determined. With piperidine (pip) a mononuclear 1:2 adduct is formed, AlCl3·2pip, in which the nitrogen atoms are axial in a trigonal-bipyramidal array about the metal: Al-N 2.070(5), Al-Cl 2.162(3)-2.190(3) Å. Attempts to crystallize the material from acetonitrile resulted in the formation of [Al{HN=C(Me)N(CH2)5}4]Cl 3·MeCN which has implications in the formation of amidines catalysed by AlCl3; Al-N 1.851-1.857(4) Å. With 2-methylpyridine, 2-diphenylmethylpyridine and quinoline, 1:1 adducts are obtained, the latter being also monosolvated: Al-N 1.942(4), 1.954(4), 1.959(6); Al-Cl (over all three), 2.082(2)-2.112(4) Å. The structure of AlCl3(thf) (thf = tetrahydrofuran) was also determined: Al-O 1.798(6), Al-Cl 2.098(4), 2.095(3) (x2) Å.
