8-Hydroxyquinaldinic acid and its nickel(II) complex

N. Okabe and Y. Muranishi

Abstract: The molecules of 8-hydroxyquinolinium-2-carboxylate, C₁₀H₇NO₃, have a planar structure, in which the carboxyl group is ionized and the ring N atom is protonated. The derived nickel(II) complex, bis(8-hydroxyquinoline-2-carboxylato- [kappa] ³O²,N,O⁸)nickel(II) trihydrate, [Ni(C₁₀H₆NO₃)₂]·3H₂O, contains an octahedral central Ni^II ion coordinated by the hydroxyl O atom, the ring N atom and the carboxylate O atom of each of the two tridentate ligands, with a perpendicular orientation of the quinoline rings.

Formula: C₁₀H₇NO₃ and [Ni(C₁₀H₆NO₃)₂]·3H₂O
