Abstract
The paramagnetic heterocycles N(R)C2H2N(R)GaI2 (R = 2,6-dimethylphenyl (1), 2,4,6-trimethylphenyl (2), and 2,6-diisopropylphenyl (3)) were obtained by reaction of "GaI" with Xyl-dab (N,N'-bis[2,6-dimethylphenyl]-1,4-diazabuta-1,3-diene), Mes-dab (N,N'-bis[2,4,6-trimethylphenyl]-1,4-diazabuta-1,3-diene), and Dipp-dab (N,N'-bis[2,6-diisopropylphenyl]1,4-diazabuta-1,3-diene), respectively. Compounds 1-3 were characterized structurally by X-ray crystallography. ESR investigations of 3 and quantum chemical calculations for the parent system NHC2H2NHGaI2 were carried out to provide information on the bonding. The reaction of 1 with 1 equiv of the 1,4-dilithiated Xyl-dab led to the formation of Ga(Xyl-dab)(2) (4) with one singly and one doubly reduced ligand; this compound was also characterized by X-ray crystallography.
