Abstract: The title coordination compound of cobalt(Ⅱ) ion with 3,5-pyridinedicarboxylic acid(Pydc) acid was synthesized and its crystal structure was determined. It crystallizes in triclinic system, P-1 space group, a=0.684 93(14) nm, b=0.939 69(19) nm, c=0.981 7(2) nm, α=90.96(3)°, β= 91.72(3)°, γ=99.82(3)°, Z=2. Cobalt(Ⅱ) ion coordinates with the N atom of 3,5-Pydc and five O atoms of water molecules in octahedral geometry. A 3-dimesional framework is formed by hydrogen bonds between carboxylic O atoms of 3,5-Pydc and O atoms of water.

Key words: Pyridinedicarboxylic acid, Coordination compound, Crystal structure
