| Popis: | Dimethylaluminum and gallium alkoxides of the type Me 2 MOR * were synthesized (M = Al; R = CH(CH 3 )CH 2 NMe 2 ( 1 ), CH(CH 3 )CH 2 NH 2 ( 2 ), M = Ga; R = CH(CH 3 )CH 2 NMe 2 ( 3 )) by reaction of Me 3 M (M = Al; Ga) with the corresponding amino alcohols. The resulting compounds 1–3 have been characterised by 1 H, 13 C and 27 Al NMR spectroscopy. The crystal structures of 1–3 were determined by X-ray diffraction. Compounds 1–3 were proved to be dimeric in solid state containing five-membered heterocyclic rings. 3 crystallises in the monoclinic space group P2 1 / n with Z = 4, a = 7.898( 2 ), b = 15.512(9), c = 8.453(2) A, and β = 103.70(2)°, V = 1000.1(9) A 3 . The Ga-N distance in 3 runs to 2.525(2) A which is significantly longer than the Al-N distances in the investigated Al compounds 1 and 2 (2.246(2) and 2.172(3) A). |
