Extraction of microamounts of cesium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of dibenzo-21-crown-7 (DB21C7, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+and CsL+are extracted into the organic phase.

1. Study of isotopic hydrogen exchange in π-cyclopentadienyl-π-dicarbollylcobalt in basic solution has shown that the hydrogen of the C-H bond of the dicarbollyl ligand enters into reaction 100 times more rapidly than the hydrogen of the cyclopentadienyl ligand. 2.
