چکیده
The title compound, (C(2)H(10)N(2))[Ni(C(16)H(14)N(2)O(2))](4)(ClO(4))(2)·C(3)H(7)NO, crystallizes with four Ni(salen) mol-ecules {salen is 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate}, one ethyl-enediammonium cation (actually two half-cations, each located on a center of inversion), two perchlorate anions and one dimethyl-formamide solvent mol-ecule in the asymmetric unit. Each Ni(II) cation in the Ni(salen) complex is four-coordinated by two imine N atoms and two phenolate O atoms from the tetra-dentate 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 inter-molecular hydrogen bonds between the ammonium H atoms and the perchlorate and salen O atoms, which generate a three-dimensional structure.
