[N,N'-bis(salicylidene)-2,2-dimethyl-1,3-propanediaminate]nickel(II) and [N,N'-bis(salicylidene)-2,2-dimethyl-1,3-propanediaminate]copper(II).

In the title compounds, [2,2'-[2,2-dimethyl-1,3-propanediylbis(nitrilomethylidyne)]diphenolato-kappa4N,N',O,O']nickel(II), [Ni(C19H20N2O2)], and [2,2'-[2,2-dimethyl-1,3-propanediylbis(nitrilomethylidyne)]diphenolato-kappa4N,N',O,O']copper(II), [Cu(C19H20N2O2)], the Ni(II) and Cu(II) atoms are coordinated by two iminic N and two phenolic O atoms of the N,N'-bis(salicylidene)-2,2-dimethyl-1,3-propanediaminate (SALPD2-, C17H16N2O2(2-)) ligand. The geometry of the coordination sphere is planar in the case of the Ni(II) complex and distorted towards tetrahedral for the Cu(II) complex. Both complexes have a cis configuration imposed by the chelate ligand. The dihedral angles between the N/Ni/O and N/Cu/O coordination planes are 17.20 (6) and 35.13 (7) degrees, respectively.
