Diaquabis{2-[2-(isopropylammonio)ethyliminomethyl]-6-methoxyphenolato}nickel(II) dinitrate dihydrate

Abstract

The title compound, [Ni(C13H20N2O2)2(H2O)2](NO3)2·2H2O, consists of a mononuclear nickel(II) complex, two nitrate anions and two solvent water mol­ecules. The Ni atom lies on an inversion centre and is chelated by the phenolic O and imine N atoms from two Schiff base ligands, and coordinated by the O atoms from two water mol­ecules, giving a slightly distorted octa­hedral geometry. Within the crystal structure, the components form chains parallel to the a axis by inter­molecular N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds.
