Abstract:

The initial employment of 1,3-propanediol (pdH2) in the synthesis of 3d/4f metal clusters has afforded a new family of tetranuclear [Mn2Ln2O2{(CH3)3CCO2}8{(CH3)3CCO2H}2(pdH2)2] (Ln = Dy, 1; Gd, 2; Ho, 3) complexes. Compounds 1-3 represent new additions to the small family of MnIII 2Ln2 clusters possessing planar or diamond-like cores. Variable-temperature, dc and ac magnetization measurements were performed on compounds 1-3 and revealed the existence of very weak antiferromagnetic exchange interactions between the metal centers leading to a ground state spin value S = 5 in case of 2·2(CH3)3CCO2H·2H2O.

Keywords: 1, 3-propanediol, 3d/4f clusters, crystal structures, magnetic properties.
