Reaction of Me3In with 5, 6-benzoquinoline (1:1 molar ratio) resulted in the formation of the Lewis acid-base adduct Me3In(BQ)2. This adduct is much less air and moisture sensitive than the trialkyl indium. It was found to be a discrete 1:2 molecular adduct of trimethylindium. The stereochemistry about 5-coordinated indium is trigonal bipyramidal. 1H NMR spectra of the adduct revealed a downfield shift of the metal alkyl protons. The complex crystallizes in the orthorhombic space group Pbcn with a = 16.672(4), b = 7.537(4), c = 18.969(3)Å and Z = 4. The structure was refined to R = 0.040 for 1732 observed reflections. The In-N bond length is 2.709(2)Å. C-In-N bond angles are in the range of 85.56(6)-92.6(1)°. This compound has a structure different to corresponding BQ adducts with Me3Al and Me3Ga. |
