Two new cobalt(II) supramolecular complexes [Co(4,4’-bipy)2(H2O)4]·[Co2(4,4’-bipy)3- (H2O)8]·2TST·2(4,4’-bipy)·4H2O 1 and [Co(4,4’-bipy)2(H2O)4]DSNT·4,4’-bipy 2 based upon the assembly of Co(II), 4,4’-bipyridine (4,4’-bipy) and two new multifunctional organic ligands, 2,4,6-tris(4-sulfophenyl- amino)-1,3,5-triazine (H3TST) and 2,4-bis(p-sulfanilato)-6-diethylamino-1,3,5-triazine (H2DSNT), have been prepared by hydrothermal method and characterized by elemental analysis, IR spectrum, and single-crystal X-ray diffraction. The crystal structure of 1 is of monoclinic, space group P21/n with a = 13.599(4), b = 18.988(6), c = 22.995(7) , β = 90.273(6)°, V = 5938(3) 3, Z = 4, C56H59Co1.5N13O17S3, Mr = 1370.74, Dc = 1.533 g/cm3, μ = 0.613 mm-1, F(000) = 2842, GOOF = 1.018, the final R = 0.0796 and wR = 0.1498 for 9019 observed reflections with I > 2σ(I). The crystal structure of 2 belongs to the monoclinic system, space group C2/c with a = 18.864(6), b = 14.283(5), c = 20.246(7) , β = 107.799(6)°, V = 5194(3) 3, Z = 4, C49H52CoN12O10S2, Mr = 1092.08, Dc = 1.397 g/cm3, μ = 0.480 mm-1, F(000) = 2276, GOOF = 1.059, the final R = 0.0665 and wR = 0.1900 for 4887 observed reflections with I > 2σ(I). The results of X-ray crystal structure analysis revealed that complexes 1 and 2 exhibit layered supramolecular frameworks stabilized by electrostatic interactions, π-π interactions and hydrogen bonds.
