Crystal structure of {N1,N3-big[(1-benzyl-1H-1,2,3-triazol-4-yl)methylidene]-2,2-dimethylpropane-1,3-diamine}bis(tinocyanato-κN)iron(II)

The unit cell of the title compound, [Fe-II(NCS)(2)(C25H28N8)], consists of two charge-neutral complex molecules related by an inversion centre. In the complex molecule, the tetradentate ligand N-1,N-3-bis[(1-benzyl-1H-1,2,3-triazol-4-yl)methylene]-2,2-dimethylpropane-1,3-diamine coordinates to the Fe-II ion through the N atoms of the 1,2,3-triazole moieties and aldimine groups. Two thiocyanate anions, coordinating through their N atoms, complete the coordination sphere of the central ion. In the crystal, neighbouring molecules are linked through weak C-H center dot center dot center dot pi, C-H center dot center dot center dot S and C-H center dot center dot center dot N interactions into a two-dimensional network extending parallel to (011). The intermolecular contacts were quantified using Hirshfeld surface analysis and two-dimensional fingerprint plots, revealing the relative contributions of the contacts to the crystal packing to be H center dot center dot center dot H (35.2%), H center dot center dot center dot C/C center dot center dot center dot H (26.4%), H center dot center dot center dot S/S center dot center dot center dot H (19.3%) and H center dot center dot center dot N/N center dot center dot center dot H (13.9%).
