Abstract
Reduced 2,2'-bipyridine (bipy-.bul.) forms paramagnetic complexes with organometallic cations RnM+ (M = metals of the first three groups of the periodic system; n = 0, 1, 2; R = Ph, Me). The persistent radicals (RnM)bipy.bul. have been identified and studied by high resoln. ESR. Their ESR coupling consts. can be correlated excellently with results from HMO calcns. and exhibit a typical sequence of cations RnM+: K+, Na+, Li+, PhMg+, PhZn+, Me2Ga+, PhBe+, Ph2B+, R2Al+. This series exemplifies the continuous variation from genuine paramagnetic \dqion pairs\dq to mostly covalently bonded radical complexes. on SciFinder(R)
