Me3Si?X (X=CN, N3, OCN, and SCN) was treated with the Lewis acids GaCl3 and B(C6F5)3 in toluene yielding the desired adducts Me3Si?X→GaCl3 and Me3Si?X→B(C6F5)3. All synthesized adducts were isolated and completely characterized including single crystal structure elucidations. The different structures, thermodynamics of formation and charge transfer effects are discussed on the basis of experimental and theoretical data.

The new compounds [K(18-crown-6)][SCNB(C6F5) 3] (1), [K(18-crown-6)][(C6F5) 3B(μ-NC)B(C6F5)3] (2), [K(18-crown-6)][NCB(C6F5)3] (3), [Me 3Si(μ-NC)B(C6F5)3] (4) and [Hg{(μ-CN)B(C6F5)3}2] (5) have been synthesised. Reaction between [IrCl(PPh3)2(CO)] and one equivalent of 4 gives [Ir{(μ-NC)B(C6F5) 3}(PPh3)2CO] (6). Similarly, the reaction between [Fe(η-C5H5)(CO)2Cl] and 4 gives [Fe{(μ-NC)B(C6F5)3}(η-C 5H5)(CO)2] (7a). The NMR-scale reaction between [Fe(η-C5H5)(CO)2CN] and B(C 6F5)3 gives the isomer [Fe{(μ-CN)B(C 6F5)3}(η-C5H 5)(CO)2] (7b). In the compounds 3, 4, 6 and 7a the anion [NCB(C6F5)3]- is coordinated to the metal through the nitrogen. Complexes 1, 2 and 7b incorporate a (μ-CN)B unit. The compounds containing the isomeric bridging (μ-CN)B or (μ-NC)B systems have been investigated by 11B{1H} NMR spectroscopy and by DFT calculations. The 11B{1H} NMR spectra enable distinction between the isomers. The single-crystal X-ray structures of 1, 3 and 7a have been determined. The Royal Society of Chemistry 2003.
