Diaquabis{2,4-dibromo-6-[2-(isopropylammonio)ethyliminomethyl]phenolato}nickel(II) dichloride hemihydrate

Abstract

The title complex, [Ni(C12H16Br2N2O2)2(H2O)2]Cl2·0.5H2O, consists of a centrosymmetric mononuclear nickel(II) complex cation, two symmetry-related chloride anions and a half-occupancy water molecule. The Ni atom, lying on an inversion centre, is six-coordinated by two phenol O atoms, two imine N atoms from two Schiff base ligands, and the O atoms from two water molecules, forming an octahedral geometry. Adjacent molecules are linked through intermolecular hydrogen bonds, forming chains running along the b axis.
