Competing Routes in the Extraction of Lanthanide Nitrates by 1,10-Phenanthroline-2,9-diamides: An Impact of Structure of Complexes on the Extraction

ABSTRACT: The fact of the fracture of the extraction curve of lanthanides by 1,10-phenanthroline-2,9-diamides is explained in terms of the structure of complexes, solvent extraction data and quantum chemical calculations. The solvent extraction proceeds in two competing directions: in the form of neutral complexes LLn(NO3)3 and in the form of tight ion pairs {[LLn(NO3)2 H2O]+ (NO3−).

The impact of alicyclic substituents on the extraction ability of new family of 1,10-phenanthroline-2,9-diamides.

Project description:Development of efficient extractants for the separation of actinides and lanthanides in the technologies of nuclear fuel cycle is one of the most urgent and complex tasks in modern nuclear energetics. New family of 4,7-dichloro-1,10-phenanthroline-2,9-dicarboxylic acid diamides based on cyclic amines was synthesized and shown to exhibit high selectivity in the La/Am pair separation (SF (Am/La ≈ 10)) and in the Am/Eu pair separation (SF (Am/Eu ≈ 12)). It was shown that pyrrolidine derived diamide is more efficient extractant for americium, curium and lanthanides from highly acidic HNO3 solution than its non-cyclic N,N,N',N'-tetraalkyl analogues. The structures of synthesized compounds were studied in details by IR, NMR spectroscopy, and single crystal X-ray diffraction. According to spectroscopy data, incorporation of aromatic rings to the amide fragment of ligand leads to complex dynamic behavior in solutions what is believed to strongly affect the extraction ability of synthesized ligands.

First 24-Membered Macrocyclic 1,10-Phenanthroline-2,9-Diamides-An Efficient Switch from Acidic to Alkaline Extraction of <i>f</i>-Elements.

Project description:A reaction of acyl chlorides derived from 1,10-phenanthroline-2,9-dicarboxylic acids with piperazine allows the preparation of the corresponding 24-membered macrocycles in good yield. The structural and spectral properties of these new macrocyclic ligands were thoroughly investigated, revealing promising coordination properties towards f-elements (Am, Eu). It was shown that the prepared ligands can be used for selective extraction of Am(III) from alkaline-carbonate media in presence of Eu(III) with an SFAm/Eu up to 40. Their extraction efficiency is higher than calixarene-type extraction of the Am(III) and Eu(III) pair. Composition of macrocycle-metal complex with Eu(III) was investigated by luminescence and UV-vis spectroscopy. The possibility of such ligands to form complexes of L:Eu = 1:2 stoichiometry is revealed.

2,9-Dichloro-1,10-phenanthroline.

Project description:The title mol-ecule, C(12)H(6)Cl(2)N(2), is almost planar (the r.m.s. deviation of C atoms is 0.04 Å). The C-N and C-C distances indicate delocalization of the π-electrons in the aromatic fused-ring system.

Aqua-(2,9-dimethyl-1,10-phenanthroline-κN,N')bis-(2-hydroxy-benzoato-κO)manganese(II) 2,9-dimethyl-1,10-phenanthroline hemisolvate.

Project description:In the asymmetric unit of the title complex, [Mn(C(7)H(5)O(3))(2)(C(14)H(12)N(2))(H(2)O)]·0.5C(14)H(12)N(2), the Mn(II) ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) mol-ecule, one water mol-ecule and two monodentate 2-hydroxy-benzoate anions in a distorted trigonal-bipyramidal geometry. The OH group of the 2-hydroxy-benzoate anion is disordered over two positions with site-occupancy factors of 0.5. The asymmetric unit is completed with by an uncoordinated half-mol-ecule of dmphen, disordered about a crystallographic twofold axis. In the crystal structure, mol-ecules are linked into a two-dimensional framework by O-H⋯N, O-H⋯O and C-H⋯O hydrogen bonds. The packing of the structure is further stabilized by π-π stacking inter-actions involving dmphen mol-ecules, with centroid-centroid separations of 3.8027 (3) and 3.6319 (3) Å.

(2,9-Dimethyl-1,10-phenanthroline-κN,N')diiodidocadmium.

Project description:In the title compound, [CdI(2)(C(14)H(12)N(2))], the mol-ecule sits on a crystallographic twofold axis. The coordination sphere of the Cd(II) atom is built of two symmetry-equivalent N atoms of one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and two symmetry-equivalent I atoms, thus forming a distorted tetra-hedral geometry. Inversion-related mol-ecules inter-act along the c-axis direction by π-π stacking inter-actions between the phenanthroline ring systems, with centroid-centroid distances of 3.707 (9) and 3.597 (10) Å.

2,9-Bis(trichloro-meth-yl)-1,10-phenanthroline.

Project description:The asymmetric unit of the title compound, C(14)H(6)Cl(6)N(2), contains two crystallographically independent mol-ecules, each of which is slightly twisted from planarity. The dihedral angles between the central ring and the two outer rings are 3.81 (7) and 4.30 (7)° in one mol-ecule, and 4.13 (8) and 4.10 (7)° in the other. In the crystal structure, mol-ecules are inter-linked by C-Cl⋯Cl inter-actions into sheets parallel to the ac plane. These sheets are stacked along the b axis in such a way that the mol-ecules are anti-parallel; they are further connected into a supra-molecular network. There are no classical hydrogen bonds. C⋯Cl [3.637 (2) Å], Cl⋯Cl [3.5639 (5)-3.6807 (8) Å] and Cl⋯N [3.3802 (15)-3.4093 (15) Å] short contacts and π-π inter-actions, with centroid-centroid distances in the range 3.5868 (9)-3.7844 (9) Å, are observed.

Sequestration of trivalent americium and lanthanide nitrates with bis-lactam-1,10-phenanthroline ligand in a hydrocarbon solvent.

Project description:Efficient separation of minor actinides and lanthanides from used nuclear fuel could potentially lead to the development of sustainable nuclear fuel cycles. Herein, we report an in-depth study on selectivity and speciation in the extraction of the trivalent minor actinide Am and rare earth metal ions with a pre-organized phenanthroline-based ligand in a hydrocarbon solvent system relevant to nuclear fuel reprocessing. The 1 : 1 and 2 : 1 ligand-to-metal complexes dominate the speciation in the organic solvent over a range of ligand-to-metal concentrations, as evidenced by experimental data and supported by modeling.

Project description:In the title compound, [MnCl(2)(C(14)H(12)N(2))]·0.5H(2)O, all of the non-H atoms apart from the Cl atom lie on a mirror plane and the methyl H atoms are disordered over two sites of equal occupancy about the mirror plane. The Mn(II) ion is coordinated in a distorted tetra-hedral environment by two N atoms of the phenanthroline ligand and two chloride ions. A half-occupancy solvent water mol-ecule lies on a mirror plane and close to an inversion center.

Dibromido(2,9-dimethyl-1,10-phenanthroline-?N,N')cadmium.

Project description:In the title complex, [CdBr(2)(C(14)H(12)N(2))], the Cd(II) ion is tetra-coordinated by two N atoms of the bidentate 2,9-dimethyl-1,10-phenanthroline ligand and two bromide ions in a substanti-ally distorted CdN(2)Br(2) tetra-hedral geometry. In the crystal, inversion dimers linked by pairs of weak C-H?Br bonds generate R(2) (2)(14) loops. Aromatic ?-? stacking [shortest centroid-centroid separation = 3.633?(2)?Å] inter-actions occur within, and also link, the dimers into chains propagating parallel to [100].
