Abstract
Reactions of LiAlR4 and LiGaH4 with Me 3SiNCNSiMe3 yield, respectively, the monomeric hexacoordinate Al(Me3SiNCHNSiMe3)3 (1) and Ga(Me3SiNCHNSiMe3)3, (2) metal amidinate compounds. A unique feature of the work is the creation of the previously unknown bidentate [Me3SiNCHNSiMe3] anion ligand which shows the propensity to fully encapsulate the Al and Ga metal centers despite potential steric crowding associated with the six-fold coordination. Compound 1 was also obtained by the reaction of (Me3N)AlH3 with Me3SiNCNSiMe3 via displacement of NMe3 followed by reduction of the carbodiimide group. The structural properties of 1 and 2 derived from single crystal X-ray diffraction are elucidated and compared with various coordination analogs.
