A novel slipped triple-decker complex with a 3,4-diborafulvene as bridging ligand.
Reaction of the 3,4-diboratafulvene deriv. Li2[CH2C[CHB(NEt2)]2] (I) with [RhCl(COD)]2 (COD = cyclooctadiene) gives m-[1-5-h5:1,2,5,6-h4-[CH2C[CHB(NEt2)]2]][Rh(h-COD)]2 (II), the first 3,4-diborafulvene complex which possesses a doubly-opened triple-decker structure with a bridging 3,4-diborafulvene ligand. The crystal structure of II was detd. I serves as a gallium nitride precursor.
