Abstract / Description of output

The solvothermal reaction of FeCl₂ ⋅ 4H₂O and H₄TBC[4] in a basic dmf/EtOH solution affords an [Fe^III₁₈] Keplerate conforming to a stellated cuboctahedron. Magnetic and heat capacity measurements reveal spin frustration effects arising from the high symmetry. A crossover between inverse and direct magnetocaloric effects is observed at ~10 K for applied-field changes lower than 3 T.
