Dysprosium Thiocyanate Complexes with s-Triazine

Resumo

The reaction of Dy(NCS)₃ · 6H₂O with 2,4,6-tris(2-pyridyl)-s-triazine (Tptz) in МеОН, MeCN, and H₂O affords mononuclear neutral and ionic thiocyanate complexes with tridentate ligand Tptz: [Dy(H₂O)(MeOH)(Tptz)(NCS)₃] · Tptz (I), [Dy(Tptz)₂(NCS)₃] · MeCN (II), and [Dy(H₂O)₃-(Tptz)(NCS)₂] · NCS · Tptz · 1.5H₂O · 1.25MeOH (III). Structural features of the synthesized compounds are determined using powder XRD, IR spectroscopy, and thermoanalytical methods (thermogravimetry and differential scanning calorimetry). Compounds II and III exhibit the properties of single-molecule magnets.
