Syntheses,Structures and Magnetic Properties of Two Co(II) Coordination Polymers with 2,5-Pyridine Dicarboxylic Acid |

| Abstract: | The hydro(solvo)thermal reactions of cobalt powder or its chloride with 2,5pyridine dicarboxylic acid (H2PYDC) yielded two new complexes: Co(II)2(PYDC)2(H2O)2(H2O)4]n 1 and {Co(II)NH2(CH3)2]2(PYDC)2}n 2. It is observed that the reactive solvents result in different connectivity modes of ligand and diverse dimensional extension of crystal structures. The correlation between structure and magnetic property will be discussed in this paper. Crystal data for 1: space group P, a = 7.0419(17), b = 8.937(2), c = 9.6182(19)A, α = 91.532(4), β = 99.869(10), γ = 107.889(11)o, V = 565.5(2)A3, Z = 1, Dc = 1.845 g/cm3, μ= 1.56 mm-1, F(000) = 322 , R = 0.0505 and wR = 0.1580; and those for 2: space group C2/c, a = 14.9075(6), b = 8.2523(3), c = 16.9643(2)A, β = 100.982(2)o, V = 2048.75(11)A3, Z = 4, Dc = 1.560 g/cm3, β = 0.892 mm-1, F(000) = 996, R = 0.0443 and wR = 0.1134. |
