A mixed-linker porphyrin framework with CdI2-type topology

A novel metal-organic framework, [(Co(cis-ZnDCPP)(bpy)]. 4DMF.H2O(cis-ZnDCPP = zinc 5,10-di(4-carboxyphenyl)-15,20-diphenylporphyrin; bpy = 4,4'-bipyridine; DMF = dimethyl formamide), has been synthesized from the solvothermal reaction and exhibits unique CdI2 layers constructed from paddle-wheel buiding units, Co-2(COO)(4), cis-ZnDCPP, and bipyridine linker.
