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-3O2,N,O8)nickel(II) trihydrate, [Ni(C10H6NO3)2]·3H2O, contains an octahedral central NiII 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
