trans-Bis(3-aminopyridine)diaquabis(4-cyanobenzoato)cobalt(II) dihydrate

H.-Y. He and L.-G. Zhu

Abstract: The reaction of cobalt(II) acetate with 4-cyanobenzoic acid and 3-aminopyridine gave the title centrosymmetric complex, [Co(C₈H₄NO₂)₂(C₅H₆N₂)₂(H₂O)₂]·2H₂O. The coordination geometry around the Co^II ion is distorted octahedral, and the 4-cyanobenzoate and 3-aminopyridine ligands act in a monodentate fashion. The hydrogen bonds among the water molecules and cyano and amino groups ensure a two-dimensional hydrogen-bonding architecture.
