Mononuclear Dysprosium Thiocyanate Complexes with 2, 2′‐Bipyridine and 1, 10‐Phenanthroline: Synthesis, Crystal Structures, SIM Behavior, and Solid‐Phase Transformations. Issue 29 (10th August 2017) - Petrosyants, Svetlana P.
Abstract : Five new dysprosium complexes were synthesized and characterized: neutral Dy(NCS)3 · 6(H2 O) (1 ), [Dy(NCS)3 (H2 O)(bpy)2 ]· 0.5(bpy)· H2 O (2 ), and [Dy(NCS)3 (H2 O)(phen)2 ]· phen· 0.5H2 O (3 ), as well as ionic [Hbpy][Dy(NCS)4 (bpy)2 ]· H2 O (4 ) and [Hphen][Dy(NCS)4 (phen)2 ] (5 ). In all complexes, the metal coordination number (CN) is 8. All complexes exhibit single‐ion magnet behavior. The influence of the structural features on Δ E/k B values is discussed. The thermal behavior of the new compounds was studied under an inert atmosphere in the temperature range of 30–550 °C. The thermal stability of the complexes is determined by the presence of solvate molecules. Abstract : New molecular and anionic mononuclear complexes of Dy(NCS)3 with H2 O/bpy/phen were synthesized and characterized. All compounds exhibit single‐ion magnet (SIM) behavior. The thermal stability of the complexes is determined by the presence of solvate molecules.
