In the title coordination polymer, {[Dy(C(10)H(13)N(2)O(8))]·3H(2)O}(n), the dysprosium(III) ion is coordinated by two N atoms and six O atoms from three different (carb-oxy-meth-yl)ethyl-ene-diamine-triacetate ligands in a distorted square-anti-prismatic geometry. The ligands connect the metal atoms, forming layers parallel to the ab plane. O-H⋯O hydrogen bonds further assemble adjacent layers...
Ground-state deformations, binding energies, and potential energy surfaces have been calculated for eveneven dysprosium isotopes between 160Dy and 180Dy in the framework of density-dependent Hartree-Fock calculations with BCS pairing correlations. Further deformed Hartree-Fock with angular-momentum projection and band-mixing calculations explore the yrast spectra of the nuclides approaching the...
In this report, dysprosium fluoride (DyF3) - a material for the preparation of (Dy) metal was prepared by fluorination oxide (Dy2O3) ammonium bifluoride (NH4HF2) reagent. The effect reaction time and temperature on formation salt has been studied. phase composition crystal structure obtained products were analysed X-ray diffraction (XRD). Thermal analysis techniques applied to determine range f...
Assembly of dysprosium(iii) salts with versatile hydrazone H3L affords a variety molecular magnetic compounds from mononuclear, dinuclear, grid-like tetranuclear to linear 1D chain.
The influence of the solvent in reaction dysprosium(III) chloride hydrate with N3O2 ligand H2L (2,6-bis(2-hydroxyphenyliminomethyl)pyridine) was studied To this end, new mononuclear complex [Dy(L)Cl(H2O)2] (1) isolated absolute ethanol as solvent, without any evidence hydrolysis ligand. This clearly contrasts previous results, where a similar methanol proceeds partial Schiff base, and formation...
Two new sandwich-type lanthanide complexes with the general formula [(Pc)2Ln3(L)(OAc)(OCH3)2] (Ln(3+) = Dy(3+) () and Er(3+) ()) were successfully synthesized and structurally characterized based on closed-macrocyclic Schiff base and phthalocyanine molecules. The magnetic properties and structure-property relationship in this multi-decker system were investigated. Interestingly, the correspondi...
