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.
