Abstract
The structure of the high-nuclearity organometallic platinum cluster material Pt-309(phen*)(36)O-30 has been investigated by X-ray absorption spectroscopy. Analysis of Pt L-3-edge EXAFS data, using platinum foil as a reference, shows that the platinum clusters have cubic close packed geometry. A slight contraction of the Pt-Pt bond length from the bulk was observed. XANES analysis shows that the platinum atoms in the clusters have a low mean oxidation state, very close to that in metallic platinum. (C) 1999 Elsevier Science S.A. All rights reserved.
