Abstract:

Two complexes, Cu(HnicO)2 1 and Ni(HnicO)2(H 2O)2 2 (H2nicO = 2-hydroxynicolinic acid), were synthesized by hydrothermal reactions and structurally characterized. Complex 1 crystallizes in monoclinic, space group P21/n, with a = 8.314(7), b = 6.275(4), c = 11.283(7) Å, β = 98.32(3)°, V = 582.5(7) Å3, Z = 2, Mr = 339.74, Dc = 1.937 g/cm3, F(000) = 342, μ = 1.908 mm-1, S = 1.097, the final R = 0.0284 and wR = 0.0781 for 1177 observed reflections with I > 2σ(I). Complex 2 crystallizes in monoclinic, space group P21/c, with a = 7.438(5), b = 12.22(1), c = 7.537(5) Å, β = 100.07(3)°, V = 674.3(8) Å3, Z = 2, Mr = 370.95, Dc = 1.827 g/cm3, F(000) = 380, μ = 1.487 mm-1, S = 1.041, the final R = 0.0335 and wR = 0.0779 for 1202 observed reflections with I > 2σ(I). There are extended 3D framework structures in complexes 1 and 2 due to the N-H⋯O and C-H⋯O hydrogen bonds. The copper atom in 1 has square planar coordination, while the nickel atom in 2 adopts octahedral coordination geometry. The TG curve shows that complex 2 is stable in solid state to 150 °C.
