The title compounds, ¿4,4'-dibromo-2,2'-[1, 3-propanediylbis(nitrilomethylidyne-N)]diphenolato-O,O '¿nickel(II), [Ni(C(17)H(14)Br(2)N(2)O(2))], and ¿4,4'-dichloro-2,2'-[1, 3-propanediylbis(nitrilomethylidyne-N)]diphenolato-O,O '¿copper(II), [Cu(C(17)H(14)Cl(2)N(2)O(2))], lie on crystallographic twofold axes. In both structures, the metal coordination sphere is a tetrahedrally distorted square plane formed by the four-coordinate N(2)O(2) 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) A, respectively, while in the Cu compound, the Cu-O and Cu-N distances are 1.907 (2) and 1.960 (2) A, respectively. The two Schiff base moieties, which themselves are nearly planar, are inclined at an angle of 29.26 (7) degrees for the Ni compound and 29.26 (5) degrees for the Cu compound.
