Temperature-controlled two new Co(II) compounds with distinct topological networks: Syntheses, crystal structures and catalytic properties

Reported here are two new Co(II) coordination polymers, namely [Co2(bptc)(bpp)2]n (1) and [Co(bptc)0.5(bpp)]n (2) (H4bptc = biphenyl-3,3′,5,5′-tetracarboxylic acid, bpp = 1,3-di(4-pyridyl)propane), which were hydrothermally synthesized from the same reactants via tuning the reaction temperature. Single crystal X-ray diffraction analyses revealed that both 1 and 2 feature 2D sheet motifs with distinct topological networks, which show high catalytic activities for degradation of methyl orange (MO) in a Fenten-like process.255
