Assembly of hexamolybdenum metallic clusters on silicon surfaces

Abstract

Becoming attached: Mo6Ii8 (Ii = inner iodine) cluster cores are anchored in apical positions to monocrystalline silicon surfaces. The attachment occurs via pyridine groups, end-capping an alkyl monolayer which is covalently bound to the hydrogen-terminated silicon surface. Octahedral Mo6 clusters: orange; pyridine head groups of the monolayer: green; apical pyridine units: blue. (Figure Presented). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
