Triaqua­[N‐(5‐formyl­salicyl­idene)glycinato(2−)‐κ3O,N,O′]cobalt(II) monohydrate

In the title complex, [Ni(C10H7NO4)(H2O)3]·H2O, a mononuclear nickel(II) compound, the NiII atom is six-coordinated in an octa­hedral geometry by the imine N, the phenolate O and a carboxyl O atom from the tridentate Schiff base ligand, and by three O atoms from three coordinated water mol­ecules. In the crystal structure, the mol­ecules are linked through inter­molecular O—H⋯O hydrogen bonds, forming a three-dimensional framework.
