Abstract

Isolated quadruply bonded dimolybdenum(II,II) complexes have been grafted onto the surface of hexagonal MCM-41 mesoporous silica by diffusion of an excess of the complex salts [Mo₂(MeCN)₁₀[BF₄]₄, [Mo₂(μ- O₂CMe)₂(MeCN)₆][BF₄]₂ and [Mo₂(μ-O₂CMe)₂(dppa)₂(MeCN)₂][BF₄]₂ into calcined and dehydrated MCM-41 in dry acetonitrile at room temperature. The physical properties of the resulting unstable materials, together with the nature of the host-guest interactions and the structure of supported molybdenum species, have been characterised by means of elemental analysis, powder X-ray diffraction, N₂ adsorption, FTIR and MAS NMR (¹³C, ²⁹Si, ³¹P) spectroscopy.
