Abstract :
New organometallic 3d–4f-heterometallic carboxylates [LnIII2MnII2(μ3-OH)2(μ-O,η2-O2CCym)2(μ2-O2CCym)6(THF)4] (Ln = Dy, Ho; Cym = (η5-C5H4)Mn(CO)3) having “defective dicubane” structure were synthesized by means of partial destructive photolysis of the cymantrenecarboxylate anion in the presence of Ln3+, O2 and H2O. The magnetic susceptibilities (dc and ac) for the complexes were measured. Magnetic properties of Dy complex are indicative of its single molecule magnet behavior, complex of Ho displays slow relaxation of the magnetization at liquid helium temperature. Thermolysis of the complexes was studied by means of TG and DSC.
