Crystal structure of bis(mesityl)(pyrrol-1-yl)borane
(Int Union Crystallography, 2022) Şahin, Onur; Wallis, John D
In the crystal structure of the title compound, C22H26BN, the B atom acts to reduce the delocalization of the nitrogen lone-pair electron density into the pyrrole ring, so that the two N-C bonds increase in length to 1.4005 (14) and 1.3981 (14) A degrees. The N-B bond length is 1.4425 (15) A degrees, which is longer than a typical N-B bond because the nitrogen lone pair is not fully available to participate in the bond.
