A Salamo-type ligand 5-methoxy-4'-chloro-2,2'-[ethylenedioxybis(nitrilomethylidyne)]diphenol (H2L) and its corresponding Ni(II) complex have been synthesized. The Ni(II) complex has been characterized by single crystal X-ray crystallography. The crystal structure shows that two water molecules coordinated to the hexa-coordinated terminal Ni(II) (Ni1 and Ni1#1) atoms which lie in the N2O2 coordination sphere of the Salamo-type ligand, quadruple μ-phenoxo oxygen atoms from two L2- units coordinated to the central Ni(II) atom and two acetate anions coordinated to three Ni(II) atoms through Ni-O-C-O-Ni bridges. Thus, all the three Ni(II) atoms have distorted octahedral geometries.
