Physical properties of metal cluster compounds I: Magnetic measurements on high-nuclearity nickel and platinum carbonyl clusters

Metal-carbonyl cluster compounds are composed of macromolecules that consist of a core of metal atoms coordinated by a “shell” of CO ligands. We present susceptibility and high-field magnetization measurements on various high-nuclearity platinum and nickel clusters. The compounds display very unusua...

Summary:Metal-carbonyl cluster compounds are composed of macromolecules that consist of a core of metal atoms coordinated by a “shell” of CO ligands. We present susceptibility and high-field magnetization measurements on various high-nuclearity platinum and nickel clusters. The compounds display very unusual low-temperature magnetic behaviour, which we ascribe to quantum-size-effects arising from the discreteness of the electronic energy levels due to the small dimensions of the metal clusters (10–40 atoms). We compare our results with predictions from molecular orbital calculations.
