A novel star-shaped high-spin Fe(III) tetranuclear cluster was unexpectedly obtained by the reaction of an [FeIII(phsal)2]- anion with an Fe(II) coordination cation (H2phsal: N-(2-hydroxyphenyl)salicylaldimine). Despite a star-shaped Fe(III) tetranuclear structure similar to reported Fe(III) single molecule magnets, the present compound exhibited a bulk antiferromagnetic transition at 0.6K due to a magnetic exchange coupling through intercluster π-stacking interactions.

We have successfully prepared nanoribbons of blue potassium molybdenum bronze (K0.3MoO3) from hydrogen molybdenum bronze (H0.3MoO3) by using crystallite splitting induced by solid-phase transformation and subsequent selective growth under hydrothermal conditions. The obtained nanoribbons were single crystals with a size of ca. 100 µm x 100 nm x 10 nm, well-elongated to the crystal b axis that corresponds to the conduction direction as a quasi-one-dimensional metal. A simple deaeration procedure necessary for preparing a single phase of blue potassium bronze is also given. [ABSTRACT FROM AUTHOR]
