mu-Acetato-bis(mu-2-{[(3-chloro-2-hydroxypropyl)(2-pyridylmethyl)amino]methyl}phenolato)dinickel(II) chloride

The title salt, [Ni-2(C16H18ClN2O2)(2)(CH3COO)]Cl, features a dinuclear cation in which the Ni atoms are triply bridged by two phenolate O ligands and a bidentate acetate ligand with all of the bridging distances essentially symmetric. Each Ni atom is also coordinated by the amine N, pyridine N and hydroxy O atoms of the 2-{[(3-chloro-2-hydroxypropyl)(2-pyridylmethyl) amino]methyl} phenolate ligand which is, therefore, pentadentate. The resultant N3O3 donor sets define octahedral coordination geometries. The chloride counter-anion is connected to the cation via two Ohydroxy-H center dot center dot center dot Cl hydrogen bonds.
