Two 1D coordination polymers constructed from 3,3′,4,4′-biphenyltetracarboxylic acid and 4,4′-bipyridine: hydrothermal syntheses and photocatalytic performance

A new two-dimensional CoII coordination polymer based on bis[4-(2-methyl-1H-imidazol-1-yl)phenyl] ether and biphenyl-4,4′-diyldicarboxylic acid: synthesis, crystal structure and photocatalytic degradation activity

A novel two-dimensional CoII coordination framework, namely poly[(μ2-biphenyl-4,4′-diyldicarboxylato-κ2 O 4:O 4′){μ2-bis[4-(2-methyl-1H-imidazol-1-yl)phenyl] ether-κ2 N 3:N 3′}cobalt(II)], [Co(C14H8O4)(C20H18N4O)] n , has been prepared and characterized by IR, elemental analysis, thermal analysis and single-crystal X-ray diffraction. The crystal structure reveals that the compound has an achiral two-dimensional layered structure based on opposite-handed helical chains. In addition, it exhibits significant photocatalytic degradation activity for the degradation of methylene blue.
