Synthesis of functionalized cobaltacarboranes based on the closo-[(1,2-C2B9H11)2-3,3′-Co]− ion bearing polydentate ligands for separation of M3+ cations from nuclear waste solutions. Electrochemical and liquid–liquid extraction study of selective transfer of M3+ metal cations to an organic phase. Molecular structure of the closo-[(8-(2-CH3OC6H4O)-(CH2CH2O)2-1,2-C2B9H10)-(1′,2′-C2B9H11)-3,3′-Co]Na determined by X-ray diffraction analysis

terminal group X and one water molecule, and from the opposite side of the ligand plane the short B(8′)-HNa contact (2.26(3) Å) was found to be within bonding distance. The sodium cation is enveloped with an hydrophobic outer sphere composed of hydrophobic CH2 and CH groups of the organic substituent and BH groups of cobalt bis(dicarbollide)(1-) cage.
