1D and 2D cobalt(II) coordination polymers, [Co(2,3-dpc)(H₂O)₂]_n (1), [Co(2,5-dpc)(H₂O)₃]_n (2) and [Co(3,5-dpc)(H₂O)₂]_n (3) (dpc = dipicolinic acid dianion) have been successfully synthesized by reaction of dipicolinic acid ligands with CoF₂ in aqueous methanolic solution under hydrothermal conditions. High resolution mass spectroscopy investigation reveals the forming process of CO during the photocatalytic CO₂ reduction and the plausible mechanisms are proposed.
