  Selective chelation of bismuth radionuclide ions from a mixture including actinium radionuclide ions involves exposing a ligand to an aqueous solution that includes bismuth radionuclide ions and actinium radionuclide ions under conditions whereby the bismuth radionuclide ions selectively chelate to the ligand for form cationic complexes of the bismuth radionuclide ions. and separating the cationic complexes of the bismuth radionuclide ions from the actinium radionuclide ions. The ligands have a structure based on a 12-membered cyclen ring and may include pendant functional groups that can be derivatized with biological targeting vectors for targeted alpha therapy.

  The potentially octadentate ligand 1,4,7,10-tetrakis(pyrazol-1-ylmethyl)-1,4 dodecane (L-1) yields with cadmium(II) compounds of formula [CdL1]Y-2 (Y = BPh4, ClO4, PF6) in which the metal ion is coordinated by the eight nitrogen donor atoms of the ligand. The crystal structure of [CdL1] (BPh,), has been determined by X-ray diffraction. With zinc(II) and mercury(II) L-1 affords the compounds [ML2]Y-2 [L-2 = 1,7-bis(pyrazol-1-ylmethyl)-1,4,7,10-tetraazacyclododecane. M = Zn; Y = ClO4, PF6. M = Hg; Y = PF6] where the ligand L-2 originates from L-1 by loss of the methylpyrazole groups from two pendant arms of the macrocycle in trans positions. The compounds have been characterized by H-1 and C-13 NMR data. A variable temperature C-13 NMR study on [CdL1](PF6)(2) suggests that the cation undergoes rearrangements in solution between two geometric isomers. (C) 1997 Elsevier Science Ltd.

  The potentially octadentate ligand 1,4,7,10-tetrakis(pyrazol-1-ylmethyl)-1,4,7,10 tetraazacyclododecane (L) gives with manganese(II) the complex [MnL][PF6]2.(CH3)2CO and with iron(II) species of formula [FeLxL'1-x] [PF6]2.solvent where the ligand L' originates from L by substitution of an ethoxy group for a pyrazolyl group in one of the pendant arms of the macrocycle. The crystal structure of [MnL]-[PF6]2.(CH3)2CO has been determined by X-ray diffraction: orthorhombic, space group Pcab, with a 15.801 (6), b = 1 7.973(4), c = 26.793(3) angstrom and Z = 8. The manganese(II) atom is co-ordinated by the eight nitrogen atoms of the L ligand. X-Ray analyses on the isomorphous crystals of the iron(II) species have shown that these contain both eight- and seven-co-ordinate iron(II) in complex cations respectively formed by the L and L' ligands.
