  摘要：

  A complete series of mono-, bis-, tris- and tetrakis-(pentafluorophenyl)gallium compounds has been obtained from the reactions of GaCl3 and GaBr3 With Mg(C6F5)Br. The complexation behaviour of Ga(C6F5)3 . O(C2H5)2 With N-donor molecules has been studied; 1 : 1 adducts with pyridine, diethylamine, tert/butyl amine and aniline as well as the uncomplexed Ga(C6F5)3 and [(n-C4H9)4N][Ga(C6F5)4] have been obtained pure. All the compounds were characterized by NMR spectroscopy, mass spectrometry and elemental analysis, and some IR spectra were recorded.

  formed by interaction of E(C6F5)3 (E = B, Al, Ga, In) with excess of acetonitrile (AN) were structurally characterized. Quantum chemical computations indicate that for Al(C6F5)3 and In(C6F5)3 the formation of a complex of 1:2 composition is more advantageous than for B(C6F5)3 and Ga(C6F5)3, in line with experimental observations. Formation of the solvate [Al(C6F5)3·2AN]·AN is in agreement with predicted

  theory reveals that with an increase in the number of acceptor molecules in the DA complex, the DA bond distances increase, while the DA bond energies and Wiberg bond indexes decrease, indicating a weaker bonding. The previously reported ‘inverse’ relationship between the Lewis acidity and the capacity of a polydentate donor to complex with multiple Lewis acids is not confirmed.
