• To investigate intermolecular interactions in the solid state.

Main Methods:

• Synthesis of the [Ni(NCS)2(C17H20N4)] complex.
• Single-crystal X-ray diffraction analysis.
• Structural analysis of coordination geometry and crystal packing.

Main Results:

• The Ni(2+) ion adopts a distorted NiN6 octahedral geometry.
• The complex features a tetradentate Schiff base ligand and two trans-oriented thiocyanate ligands.
• The crystal structure exhibits statistical disorder in a ligand methyl group and aromatic π-π stacking.

Conclusions:

• The synthesized nickel(II) complex displays a unique distorted octahedral coordination.
• Ligand disorder and π-π stacking play roles in the crystal packing.
• This structural insight contributes to the understanding of Schiff base metal complexes.
