Abstrakt: The title compounds, {4,4′-di­bromo-2,2′-[1,3-propane­diyl­bis(nitrilo­methyl­idyne- N)]­diphenolato- O, O′}nickel(II), [Ni(C17­H14­Br2­N2O2)], and {4,4′-di­chloro-2,2′-[1,3-pro­pane­diyl­bis­(ni­trilo­methyl­idyne- N)]­di­phen­ol­ato- O, O′}­copper(II), [Cu­(C17­H14­Cl2­N2O2)], lie on crystallographic twofold axes. In both structures, the metal coordination sphere is a tetrahedrally distorted square plane formed by the four-coordinate N2O2 donor set of the Schiff base imine-phenol ligands. In the Ni compound, the Ni-O and Ni-N distances are 1.908 (3) and 1.959 (4) Å, respectively, while in the Cu compound, the Cu-O and Cu-N distances are 1.907 (2) and 1.960 (2) Å, respectively. The two Schiff base moieties, which themselves are nearly planar, are inclined at an angle of 29.26 (7)° for the Ni compound and 29.26 (5)° for the Cu compound. [ABSTRACT FROM AUTHOR]
