The reaction of Co(II) with 5,15-dipyridyl-10,20-diphenylporphyrin (H 2DPyP) produces the first metal-organic coordination polymer supported by a trans meso-bifunctional porphyrin ligand. Formulated empirically as [Co3(DPyP)3]·4HDMF, this compound exhibits a ribbonlike coordination network consisting of tetranuclear metalloporphyrin cages. The DMF guest molecules fill the intra-ribbon cages as well as the inter-ribbon space. Evacuation of [Co3(DPyP)3]·4DMF at 130 °C generates [Co3(DPyP)3] that retains crystallinity, as shown by its powder X-ray diffraction pattern, which is consistent with that of [Co3(DPyP)3·4HDMF.
