Abstract:
The 44 atom core Ni38Pt6 in the metal cluster compound [HNi38Pt6(CO)(48)](5-) is the largest metal atom core, that has been realized in a single crystal. By Pt-195 NMR we have studied the electron density at the Pt-core atoms in powders and single crystals of two varieties of this compound. The large line widths can be explained by charge fluctuations between the metal cores, which are about 17 Angstrom apart. The relaxation rates, which resemble those in randomly-packed Pt309 cluster compounds, confirm such an interpretation.
