Abstract

In the title complex, (6,6'-{(1E.1'E)-[ethane-1,2-diylbis(azanylylidene)bis-(methanylylidene)}bis[2-(trifluoromethoxy)phenol]-kappa(4) O,N,N',O')nickel(II), [Ni(C18H12F6N2O4)], the nickel(II) ion has a square-planar coordination sphere, being ligated by two N and two O atoms of the Schiff base ligand 6,6'-{(1E,1'E)-[ethane-1,2-diylbis(azanylylidene)]bis(methanylylidene)}bis[2-(trifluoromethoxy)phenol] (L). Inversion-related molecules are linked by a short Ni...Ni interaction of 3.2945 (6) angstrom forming a dimer. In the crystal, the dimers stack up the a axis, with a closest Ni center dot center dot center dot Ni separation of ca 3.791 angstrom. There are no other significant intermolecular interactions present. However, the Hirshfeld surface analysis and the two-dimensional fingerprint plots indicate that the packing is dominated by H center dot center dot center dot F/F center dot center dot center dot H, H center dot center dot center dot H, O center dot center dot center dot H/H center dot center dot center dot O and C center dot center dot center dot H/H center dot center dot center dot C contacts.
