In this Dalton Transactions Hot Article, En-Bo Wang and colleagues synthesised two nanosized, hexameric POM-based solid assemblies, decorated with six 3d–4f heterometallic clusters: (H2en)6Na15K9[Dy6Fe6(H2O)12(SiW10O38)6]·34H2O and K13Na17[H2en]3[Tb6Fe6-(H2O)12(SiW10O38)6]·40H2O.
The assemblies were synthesised by a hydrothermal method and characterised by IR, elemental analyses, magnetic studies and single crystal X-ray analysis. The use of organic ligands, pH and reaction temperature all play an important role in the synthesis. The magnetic studies suggest the presence of antiferromagnetic interactions in both compounds.
