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)3CCO28(CH3)3CCO2H2(pdH2)2] (Ln = Dy, 1 Gd, 2 Ho, 3) complexes. Compounds 1-3 represent new additions to the small family of MnIII2Ln2clusters 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.
