摘要 The reaction of CoCl2. 6H2O with picolinic acid gives the title compound Co-(C6NO3H4)3. H2O at room temperature. The crystallographic data for Co(C6NO3H5)3. H2O: monoclinic, space group C2/c, a= 29. 8316(6), b= 8. 573(2),c= 13. 835(3) , β= 95. 93(3)°, Z= 16, Mr=443. 3, Dc= 1. 673 g/cm3, μ(MoKa)= 1. 109 mm-1, F (000) = 1808, R =0. 036, R. =0.048 for 2497 independent observed reflections [F≥4.0σ(F)]. The Co atom is coordinated by three oxygen andthree nitrogen atoms, forming a distorted octahedral coordination geometry. In the unitcell, two kinds of isomerides are included. They are the mirror images to each other. The reaction of CoCl2. 6H2O with picolinic acid gives the title compound Co-(C6NO3H4)3. H2O at room temperature. The crystallographic data for Co(C6NO3H5)3.
