Abstract

Reactions between platinum tetra(4-carboxyphenyl)porphyrin and copper acetate in the presence of pyridine and either triethylamine or ammonium hydroxide, under solvothermal conditions, yielded 1:2 and 1:1 discrete porphyrin complexes with solvated copper ions. The latter crystallized from the respective reaction mixtures as channel-type lattice clathrates, accommodating pyridine or triethylamine in the interporphyrin channel voids. The host lattice consists of the Cu-coordinated porphyrin entities which stack one on top of the other in an offset manner at regular intervals of 3.8-4.1 Å. Side-packing of these stacks is stabilized by hydrogen-bonding interactions.
