Abstract

Molecular complexes between α-Keggin polyanions and tetraphenylporphyrinato ZnII that are uexpectedly stable have been obtained in the presence of an ancillary donor anion such as a halide. X-ray structure determination reveals intgrated organic-inorganic stacks with alkyl ammonium cations acting as spacers. Development of these compounds, which combine thermally and photochemically redox active units, may lead to molecular materials with interesting electro-and photochromic properties.
