Two coordination polymers, namely {[Co(L)(H2O)]·H2O}n(1) and [Mn(L)(phen)]n(2, H2L = 5-(pyridin-4-yl)isophthalic acid, phen = 1,10-phenanthroline), have been hydrothermally synthesized and characterized by elemental analysis, IR, TG, magnetic properties, and single-crystal X-ray diffraction. 1 belongs to the triclinic system, space group P1 with a = 7.2188(7), b = 10.0835(8), c = 10.2069(7) ?, α = 113.713(7), β = 99.490(7), γ = 104.516(8)o, V = 628.24(9) ?3, C13H11NCoO6, Mr = 336.16, Z = 2, Dc = 1.777 Mg/m3, μ(MoKα) = 1.395 mm–1, F(000) = 342, S = 1.041, the final R = 0.0381 and wR = 0.0819 for 3744 observed reflections(I > 2σ(I)) and R = 0.0448 and wR = 0.0874 for all data. 2 belongs to the monoclinic system, space group P2/c with a = 12.9185(3), b = 10.4343(2), c = 31.7650(6)?, β = 101.282(2)o, V = 4199.08(13)?3, C50H30N6Mn2O8, Mr = 952.68, Z = 4, Dc = 1.507 Mg/m3, μ(MoKα) = 5.447 mm–1, F(000) = 1944, S = 1.128, the final R = 0.1003 and wR = 0.1052 for 8247 observed reflections(I > 2σ(I)) and R = 0.2595 and wR = 0.2625 for all data. Single-crystal X-ray diffraction studies show that compound 1 features a 2D sheet structure based on a dicobalt(II) subunit, which is further extended into a 3D metal-organic supramolecular framework by O–H···O hydrogen bond. Compound 2 also possesses a 2D sheet, which is held together into a 3D supramolecular architecture via C–H···O hydrogen bond and π-π stacking interactions. Magnetic studies for compound 2 show antiferromagnetic coupling between the adjacent metal centers, with J = –11.8 cm–1 and g = 2.12 for 2.
