摘要：

The Lewis acid/base adducts [X3M.N(SnMe3)(3)] (1a: M = Al, X = Cl; 2a: M = Ga, X = Cl; 2b: M = Ga, X = Br; 3a: M = In, X = Cl; 3b: M = In, X = Br) and [Cl2MeM.N(SnMe3)(3)] (1b: M = Al, 2c: M = Ga) were prepared by the 1 : 1 mole reaction of MX3 and MCl2Me with N(SnMe3)(3) at room temperature in diethyl ether and crystallised from dichloromethane at -20 degreesC. The new compounds were fully characterised by elemental analysis, NMR spectroscopy and single crystal X-ray diffraction. Unusually short M-N bond lengths of 1.87(1) Angstrom for Al-N (1a), 1.950(7) Angstrom for Ga-N (2a) and 2.148(6) Angstrom for In-N (3a) were found indicating very strong donor-acceptor bonds.
