A variable-temperature study of 1,2-bis(dimethylamino)-1,2-bis(2,6-dimethylanilino)diborane
摘要:
The title compound, C20H32B2N4, is monoclinic at ambient temperature but triclinic (pseudo-monoclinic) below 150 K. The structures of the two phases, determined at 200 and 120 K, respectively, are very similar, the molecular symmetry being crystallographic C-2 and approximate (local) C-2, respectively. There is significant pi conjugation within each N-B-N moiety, but none between them or between the N-B-N and arene moieties.
