Abstract
Magnetic measurements of individual (manganese,sodium)phenylsilsesquioxane containing eight MnII ions were performed. The magnetic arrangement of manganese ions in this cage-like compound was investigated. The magnetic moment of the cage molecule equals 21 μB (at 300 K), that is a consequence of the mutual antiferromagnetic compensation of four MnII ions, whereas the other four MnII ions have aligned spins. Hence, this metallasiloxane is a promising compound for the chemical design of molecular nanomagnets. At low temperatures, the antiferromagnetic coupling causes a decrease in the effective magnetic moment (to 16 μB at 40 K).
