Original language description
A new series of the boron substituted cobalt bis(dicarbollide)(1-) ion (1) derivatives of the general formula closo-[(8-X-(CH2CH2O)(2)-1,2-C2B9H10)(1',2'-C2B9H11)-3,3'-Co](-) (X = 1-O-2-CH3O-C6H4 (3), 1-O-2-C6H5CH2-C6H4 (4), l-O-4-t-C8H17-C6H4 (5), -P(O)(OC4H9)(2) (6) and -P(O)(OC4H9)(OH) (7) was prepared by ring cleavage of 8-dioxane-1 derivative (2). The compounds were synthesized with the aim to develop a new class of extraction agents effective for liquid-liquid extraction of polyvalent cations,i.e. lanthanides and actinides from high level activity nuclear waste. All compounds were characterized by a combination of B-11 NMR, H-1 high field NMR methods, mass spectrometry with electrospray ionization, HPLC and other techniques. The molecular structure of the sodium salt of anion 3 was determined by single crystal X-ray diffraction analysis. Crystallographic results proved the sodium atom is tightly coordinated to five oxygen atoms of the spacer chain, the guaiacolyl terminal gro
