Abstract
The 44 atom core Ni38Pt6 in the metal cluster compound [HNi38Pt6(CO)(4 8)](5-) is the largest metal atom core, that has been realized in a si ngle crystal. By Pt-195 NMR we have studied the electron density at th e Pt-core atoms in powders and single crystals of two varieties of thi s compound. The large line widths can be explained by charge fluctuati ons between the metal cores, which are about 17 Angstrom apart. The re laxation rates, which resemble those in randomly-packed Pt309 cluster compounds, confirm such an interpretation.
