Abstract

The title compound, (C2H10N2)[Ni(C16H14N2O2)]4(ClO4)2·C3H7NO, crystallizes with four Ni(salen) mol­ecules {salen is 2,2′-[ethane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolate}, one ethyl­enediammonium cation (actually two half-cations, each located on a center of inversion), two perchlorate anions and one dimethyl­formamide solvent mol­ecule in the asymmetric unit. Each NiII cation in the Ni(salen) complex is four-coordinated by two imine N atoms and two phenolate O atoms from the tetra­dentate ligand. The Ni(salen) units form parallel slipped stacks with Ni⋯Ni separations of 3.4541 (4) and 3.6442 (6) Å. The crystal packing is stabilized by inter­molecular hydrogen bonds between the ammonium H atoms and the perchlorate and salen O atoms, which generate a three-dimensional structure.
