{6,6′-Dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethanylylidene)]diphenolato}nickel(II) dimethylformamide monosolvate

Abstract

In the title compound, [Ni(C18H18N2O4)]·C3H7NO, the central NiII atom is in a square-planar O2N2 coordination environment. The planar Ni–salen moieties (r.m.s. deviation for the plane through the conjugated part of the Ni–salen group = 0.07 Å) form parallel stacks in the a-axis direction, with alternating Ni⋯Ni separations of 3.5339 (7) and 3.6165 (7) Å. In the crystal, there are weak inter­molecular C—H⋯O inter­actions involving the dimethyl­formamide O and phenolate O atoms.
