Abstract

The mononuclear neutral complexes [Ln(Me₄Phen)₂(H₂O)(NCS)₃]·Me₄Phen·0.75EtOH (Ln = Dy, Er, Yb) were prepared for the first time by the reaction of [Ln(H₂O)₅(NCS)₃]·H₂O (Ln = Dy, Er, Yb) with 3,4,7,8-tetramethyl-1,10-phenanthroline (Me₄Phen) in ethanol. The products were identified by elemental analysis and powder X-ray diffraction. A thermoanalytical study of the products revealed the transfer of the outer-sphere Me₄Phen ligand to the first coordination sphere. The obtained compounds were found to behave as single-molecule magnets.
