Dihydrogen complexes: striking effect of ion pairing to BF(4)(-) on the rotation of coordinated dihydrogen and the (19)F relaxation time.
Unexpected changes in the T(1) values for the (19)F NMR signal of the BF(4)(-) anion in the presence of dihydrogen complexes reveal that ion pairing with BF(4)(-)...H(2) interactions of different strengths can lead to significant changes in the rotation barrier for coordinated dihydrogen.
