the synthesis of smcl3(thf)3 from smcl3.6h2o is described. the reaction of smcl3(thf)3 with nabh4 in dry thf gave white microcrystalline tris (tetrahydroborato) tris (tetrahydrofuran) samarium (iii), sm(bh4)3(thf)3. the vibrational and magnetic properties of sm(bh4)3(thf)3 have been studied.
Pure and Samarium (Sm3+) doped Mn-Zn ferrites were synthesized using Co-precipitation method. The Sm3+ concentration varied from 0.1% to 0.3%. This was added the solution during synthesis of (Mn0.5Zn0.5Fe2O4) at room temperature. precipitate so obtained annealed 200℃ for 4 h then crushed powder. powdered material subjected structural, morphological, compositional, optical magnetic characterizat...
In the title coordination polymer, [Sm(C(10)H(13)N(2)O(8))(H(2)O)](n), each samarium(III) centre is nine-coordinated by six O and two N atoms from three N'-(carboxy-meth-yl)ethyl-enediamine-N,N,N'-triacetate ligands and one O atom of a water mol-ecule, forming polymeric chains running parallel to the a axis. The packing is governed by inter-molecular O-H⋯O hydrogen-bonding inter-actions.
Well-defined lanthanide polysulfide complexes containing S4(2-) and S5(2-) ligands, the samarium(iii) pentasulfide complex Sm(Tp(iPr2))(κ(1)-3,5-(i)Pr2Hpz)(S5) and the tetrasulfide-bridged binuclear ytterbium(iii) complex (μ-S4)[Yb(Tp(iPr2))(κ(1)-3,5-(i)Pr2Hpz)(κ(2)-3,5-(i)Pr2pz)]2 (Tp(iPr2) = hydro-tris(3,5-diisopropylpyrazolyl)borate), have been synthesized and structurally characterized by s...
