Six new coordination polymers, [Co(NiL)(aipt)] (1), [Co2(ML) (hipt)2(CH3OH)(H2O)]·CH3OH (M = Cu (2), Ni (3)), [Co2(C2O4) 2(CuL)2] (4), [Co4(NiL)4(ipt) 4(H2O)2] (5) and [Co(CuL)(tpt)] (6) (H 2L = 2,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7, 13-dien; H2aipt = 5-aminoisophthalic acid; H2hipt = 5-hydroxyisophthalic acid; H2ipt = isophthalic acid; H2tpt = terephthalic acid), have been synthesized by a solvothermal method and characterized by single-crystal X-ray diffraction. Complexes 1, 4 and 5 exhibit different infinite chain structures formed by CoNi (1), Co2Cu 2 (4), Co4Ni4 (5) units, respectively, via oxamide and diverse carboxylate bridges, while complexes 2, 3 and 6 exhibit different two-dimensional network structures formed by Co2M or Co2M2 units via oxamide and 5-hydroxyisophthalate or terephthalate bridges. The results of magnetic determination show weak antiferromagnetic interactions in 1-3 and 5-6, and the spin-orbit coupling interaction of Co(II) is a primary factor in the magnetic behaviors.
