Abstract:

Two complexes, Cu(HniCO)(2) 1 and Ni(HnicO)(2)(H2O)(2) 2 (H(2)nicO = 2-hydroxynicolinic acid), were synthesized by hydrothermal reactions and structurally characterized. Complex 1 crystallizes in monoclinic, space group P2(1)/n, with a = 8.314(7), b = 6.275(4), c = 11.283(7) angstrom, beta = 98.32(3)degrees, V = 582.5(7) angstrom(3), Z = 2, M-r = 339.74, D-c = 1.937 g/cm(3), F(000) = 342, mu = 1.908 mm(-1), S = 1.097, the final R = 0.0284 and wR = 0.0781 for 1177 observed reflections with I > 2 sigma(I). Complex 2 crystallizes in monoclinic, space group P2(1)/c, with a = 7.438(5), b = 12.22(1), c = 7.537(5) angstrom, beta = 100.07(3)degrees, V= 674.3(8) angstrom(3), Z = 2, M-r = 370.95, D-c = 1.827 g/cm(3), F(000) = 380, mu = 1.487 mm(-1), S = 1.041, the final R = 0.0335 and wR = 0.0779 for 1202 observed reflections with I > 2 sigma(I). There are extended 3D framework structures in complexes 1 and 2 due to the N-H center dot center dot center dot O and C-H center dot center dot center dot 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 degrees C.
