A new polymeric framework formed by the self assembly of 5,10,15,20-tetra(3-pyridyl)porphyrin, HgI2 and C60

The X-ray structure of H2T(3-Py)(PHgI2C60)-Hg-.-C-., cocrystallized from a chlorobenzene/methanol solvent mixture containing 5,10,15,20-tetra(3-pyridyl)porphyrin, HgI2 and C-60, has been determined. A new two dimensional arrangement of the tetra(3-pyridyl)porphyrin molecules joined by coordination to HgI2 is formed. These assemblies are connected by close C-60-Porphyrin pi-pi interactions leading to the alignment of the porphyrins into linear alternating fullerene porphyrin columns. The structure is compact with no significant cavities.
