Two novel 2-fold interpenetration frameworks constructed by 4,4′-bis(1H-imidazol-1-yl-methyl)biphenyl cobalt(II) coordination polymer and the effect of dicarboxylic acid

To investigate the construction of interpenetrating frameworks, tow novel coordination polymers were hydrothermally synthesized. The results indicate that the coordination polymers based on long spacer bimb ligand are inclined to form interpenetrating structures, which can be tuned by 1,2-benzenedicarboxylic acid as the second ligand from 2-fold interpenetrating pcu framework to 2-fold interpenetrating uoc framework.
