Abstract:A heterometallic phenylsilsesquioxane (PhSiO1,5)22(CoO)3(NaO0.5)6]?(EtOH)6?(H2O) 1 cage architecture of CoII ions in a triangular topology exhibits a slow dynamic behavior in its magnetization, induced by the freezing of the spins of individual molecules.
Keywords:cage compounds  cobalt  metallasilsesquioxanes  spin glasses
