A new route to dilithio boraamidinates: formation and X-ray structures of the dimeric and trimeric clusters {Li2[RB(NBut)2]}x (R = Bun, x = 2 and R = Me, x = 3)
Abstract
The dilithio boraamidinate complexes {Li2[RB(NBut)2]}x (R = Bun, x = 2 and R = Me, x = 3), prepared unexpectedly by treating B[N(H)But]3 with 3 equiv. LiR, represent the first structurally characterized s-block metal derivatives of the boraamidinate ion.
