Magnetic Properties of Molecular Metal Clusters

  • Robert E. Benfield


Relatively little is known of the physical properties of molecular metal cluster compounds. Magnetic susceptibility and electron paramagnetic resonance (EPR) experiments have shown that osmium carbonyl clusters of sufficiently high nuclearity have unusual “metametallic” magnetic properties. These represent a molecular analogue of the types of magnetism observed in small particles and colloids of several metals, but are beyond the ability of current theories to explain quantitatively. Results of low-temperature EPR spectroscopic measurements on several molecular cluster compounds such as H2Os 10C(C0)24 and 0s S2(CO)23 are presented, and parallels between their properties and those of non-molecular metal clusters are discussed.
