Supramolecular Assembly of Heterogeneous Multiporphyrin Arrays-Structures of [{ZnII (tpp)}2 (tpyp)] and the Coordination Polymer [{[MnIII (tpp)]2 (tpyp)(ClO4 )2 }∞ ].

Channels make up 46% of the crystal volume: A two-dimensional coordination polymer of exceptional structural regularity (see schematic drawing; tpp=tetraphenylporphyrin, tpyp=tetrapyridylporphyrin) was assembled from [MnIII (tpp)]⋅ClO4 and tpyp. The crystal packing of these polymers yields an open bulk structure with networks of perpendicular channels filled with nitrobenzene solvent molecules. Only oligomeric entities are formed by the reaction of [ZnII (tpp)] with tpyp. © 1998 WILEY-VCH Verlag GmbH, Weinheim, Fed. Rep. of Germany.
