(where X = Cl, Br, I; CMPO = Ph2P(O)-CH2C(O)(t-C8H17)N-) (4a–c), were prepared and studied for Ln(III)/An(III) group extraction. These compounds were accessible via halogenated zwitterionic amino derivatives [3,3′-Co(III)-(8-t-C8H17NH2-(CH2-CH2O)2-1,2-C2B9H10)(8′-X-1′,2′-C2B9H10)] (3a–c), prepared by several different synthetic methods. All the compounds were characterized by a combination of 11B NMR,
