Abstract

In the title compound, [Ni(C 21 H 21 Cl 4 N 3 O 2 )(C 4 H 8 O 2 )], the Ni atom has a distorted octahedral coordination geometry in which the pentadentate Schiff base ligand acts as an N 3 O 2 donor and a molecule of 1,4-dioxane occupies the remaining coordination position. The N atoms adopt a meridional arrangement, coplanar with the O-donor atom of the dioxane molecule, and the ligand O atoms are trans-related. This conformation results in an approximate square-pyramidal coordination for the pentadentate ligand, with the dioxane molecule trans to the amine N atom.
