A mixed-linker porphyrin framework with CdI2-type topology

Abstract
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, Co2(COO)4, cis-ZnDCPP, and 4,4′-bipyridine linker.
