Weak ternary CT salts formed by α‐keggin polyanions and tetraphenylporphyrinato ZnII in the presence of halide ions
Source abstract
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.

All the data were collected with a crystal measuring 0.01 × 0.07 × 0.12mm on a Rigaku AFC5R diffractometer with graphite monochromated Cu‐Kα radiation and a 12 kW rotating anode generator. The TEXAN crystallographic software package (Molecular Structure Corporation) was used for the calculations. The data were corrected for shape anisotropy. An empirical absorption correction based on azimuthal scans of several reflections was applied and the resulting transmission factors ranged from 0.59 to 1.00. The positions of the Mo atoms were obtained by Patterson synthesis subsequent Fourier syntheses gave the coordinates of all the other atoms. Only the Mo atoms were refined anisotropically. The phenyl and the pyrrole rings of the ZnTPP molecules were refined as rigid bodies. The H atoms were included at calculated positions and not refined. TheRvalues of 0.141 andRw= 0.168 withw= 1/s2 were obtained at the end of the refinement of 1139 observed reflections [F3s(F)] of the 2260 independent reflections collected (Rint= 0.174).
