Mimicking oxide surfaces: Different types of defects and ligand coordination at well defined positions of a molybdenum oxide based nanocluster

Abstract

The mixed valence cluster anion of the compound (NH4)32[MoVI110MoV28O416H6(H2O)58(CH3CO2)6]·xH2O 1 (x∼250), synthesized under one-pot conditions, contains well-defined different types of defects—missing groups compared to the complete parent {Mo154} type cluster with full D7d symmetry—and acetate ligand coordination; this proves that the giant-wheel type anion can be considered as an object with a variety of nanoscale structural features (“nanostructured landscape”) allowing reactions at a variety of well defined centers. © 2001 Royal Society of Chemistry.
