A cobalt complex [(C6H6N2O) 2Co.2H2O] .2NO3 was synthesized. The compound belongs to the monoclinic space group P2 (1) / n and its chemical formula is C12H16CoN6O10, Mr = 463.24. The unit cell parameters are a = 0.69527 (10) nm, b = 1.12250 (15) nm and c = 1.20352 (17) nm, β = 97.740 (2) °, V = 0.9307 (2) (nm) 3, Z = 2, Dc = 1.653 mg / m 3, F (000) = 474 and μ = 0.989 mm -1 The deviation factor R1 = 0.0301 and wR2 = 0.0791. Complex basic unit contains a Co (Ⅱ) ion, two molecules of pyridine amide, two molecules of coordination water and two molecules of nitrate ions. The Co2 + ion is a six-coordinated distorted octahedral configuration. In addition, there are abundant hydrogen bonds in the complex, and the hydrogen bonds between these molecules reinforce the combination of adjacent units and make the crystal appear the three-dimensional network supermolecular structure.
