Abstract

Two new two-dimensional (2D) metal–organic coordination polymers [Co(ox)(bbbm)]·H2O (1) and [Cu(ox)(bppdca)]·2H2O (2) (H2ox = oxalic acid, bbbm = 1,1-(1,4-butanediyl)bis-1H-benzimidazole and bppdca = N,N′-bis(pyridin-3-yl)-2,6-pyridinedicarboxamide) were synthesized under hydrothermal conditions and structurally characterized. Both 1 and 2 exhibit a 2D four-connected network formed by the CoII/CuII ions as four-connected nodes; and, the ox anions and bbbm/bppdca ligands as linkers with a (44.62) topology as determined by single crystal X-ray diffraction. In addition, the thermal stability, electrochemical and luminescent properties for 1 and 2 were investigated.
