Molecular complexes between α‐ Keggin polyanions and tetraphenylporphyrinato Zn II 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.
