Mimicking oxide surfaces: different types of defects and ligand coordination at well defined positions of a molybdenum oxide based nanoclusterDedicated to Prof. J. Strähle on the occasion of his 65th birthday.

Abstract

The mixed valence cluster anion of the compound (NH₄)₃₂[Mo^VI₁₁₀Mo^V₂₈O₄₁₆H₆(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 D_7d 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.
