Crystal structure and Hirshfeld surfaces analysis of the nickel(II) complex of the Shiff base ligand 6,6'-{(1E,1'E)-[ethane-1,2-diylbis(aza-nylyl-idene)]bis-(methanylyl-idene)}bis-[2-(tri-fluoro-meth-oxy)phenol].

ABSTRACT: In the title complex, (6,6'-{(1E,1'E)-[ethane-1,2-diylbis(aza-nylyl-idene)]bis(methanylyl-idene)}bis-[2-(tri-fluoro-meth-oxy)phenol]-?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(aza-nylyl-idene)]bis-(methanylyl-idene)}bis-[2-(tri-fluoro-meth-oxy)phenol] (L). Inversion-related mol-ecules are linked by a short Ni?Ni inter-action of 3.2945?(6)?Å forming a dimer. In the crystal, the dimers stack up the a axis, with a closest Ni?Ni separation of ca 3.791?Å. There are no other significant inter-molecular inter-actions present. However, the Hirshfeld surface analysis and the two-dimensional fingerprint plots indicate that the packing is dominated by H?F/F?H, H?H, O?H/H?O and C?H/H?C contacts.
