چکیده
The asymmetric unit of the title compound, [Ni(2)(C(16)H(14)N(2)O(2))(2)], contains an Ni(II) cation which is coordinated by two imine N atoms and by two phenolate O atoms of the salen ligand {salen = N,N'-bis-(salicyl-idene)ethane-1,2-diamine or 2,2'-[ethane-1,2-diyl-bis(nitrilo-methyl-idyne)]diphenol}, leading to a distorted square-planar conformation. When a secondary Ni-O inter-action > 2.41 Å to the neighbouring phenolate O atom is considered, two mol-ecules are linked into a centrosymmetric dimer with an overall square-pyramidal coordination for the Ni(II) cation. Weak π-π inter-actions with a shortest interplanar distance of 3.704 Å help to stabilize the crystal structure.

The title compound, [Fe(2)(C(16)H(14)N(2)O(2))(2)(NCS)(2)], is isostructural with the Mn(III)-containing analogue. Each Fe(III) atom is chelated by a tetra-dentate 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate ligand and by the N atom of a thio-cyanate anion, in a square-pyramidal arrangement. The complex mol-ecules form centrosymmetric dimers, with an Fe-O contact of 2.549 (3) Å, ...
