Stereoisomerization of the Ṗ(OCH2CH2)3N+BF4– radical: a single-crystal e.s.r. study
Abstract
The [graphic omitted]+BF4– radical with the unpaired electron in an apical position of the trigonal-bipyramidal (TBP) structure is generated by X-irradiation via an intermediate TBP structure in which the unpaired electron is located in an equatorial position.
