N, N’-bis (3-pyridyl) -pyridine-3,5-dicarboxamide (bppdca) and 1,4-cyclohexanedicarboxylic acid (H2L) A three-dimensional supramolecular compound [CO (bppdca) 2 (HL) 2 (H2O) 2] · 2H2O was obtained and the crystal structure of the compound was confirmed by elemental analysis, IR and single crystal X-ray diffraction The compound belongs to the monoclinic space group P21 / n with unit cell parameters of a = 0.82065 (6) nm, b = 1.25976 (9) nm, c = 2.47911 ) =, Z = 2, V = 2.537 6 (3) nm3, Mr = 1 111.98, Dc = 1.455 g / cm3 F (000) = 116 2 μ = 0.421 mm -1 S = 1.018 R = 0.041 7, wR = 0.102 3. The crystal structure analysis showed that CoⅡ in the complex formed two metal complexes with two bppdca ligands, two HL anions and two coordination water molecules, and the adjacent complex formed by hydrogen bonding Expand into three-dimensional supramolecular framework.In addition, the thermal stability, fluorescence properties and photocatalytic properties of the compound were also studied.
