  Europium and terbium thiocyanates: Syntheses, crystal structures, luminescence and magnetic properties

  摘要：

  Thiocyanates [M(H2O)(5)(NCS)(3)]center dot H2O (M(III) = Eu, Tb) and Eu-3(H2O)(12)(EtOH)(3)(NCS)(9) have been synthesized. These compounds react with 18-crown-6 to give moisture-stable polymorphous modifications of [M(18-crown-6)(NCS)(3)]. On transition from aqua complexes to complexes with the macrocycle, the coordination number of the complex-former increases from 8 to 9. Thermolysis of [M(H2O)(5)(NCS)(3)]center dot H2O in the temperature range 200-300 degrees C revealed a principal difference in the behavior of isostructural complexes of europium and terbium. Europium thiocyanate was found to undergo a redox process. The [M(18-crown-6)(NCS)(3)] ensembles maintain thermal stability up to 300 degrees C. The magnetic behavior of the [Eu(H2O)(5)(NCS)(3)]center dot H2O complex is determined by crystal field effects, while that of the Eu-3(H2O)(12)(EtOH)(3)(NCS)(9) ensemble and of the compounds containing the macrocycle is mostly governed by the properties of the free Eu(III) ion. The [M(H2O)(5)(NCS)(3)]center dot H2O complexes manifest photoluminescence under direct excitation that is typical of Eu and Tb ions. Incorporation of the 18-crown-6 macrocycle in the complexes quenches the luminescence of REE ions completely. (C) 2015 Elsevier B. V. All rights reserved.

  Abstract The integral heats of solution of nine kinds of RE(NCS) 3 · n H 2 O ( n = 6 for RE = Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Y) in aqueous glycine solution, of nine kinds of RE(NCS) 3 · n H 2 O ( n = 7 for RE = La, Pr, Nd; n = 6 for RE = Gd, Dy, Ho, Tm, Yb, Y) in aqueous alanine solution and of ten kinds of RE(NCS) 3 · n H 2 O ( n = 7 for RE = La, Pr, Nd; n = 6 for RE = Sm, Eu, Gd, Dy, Ho, Yb, Y)
