Synthesis and characterization of a linked, π-π stacked organotin compound of 2-mercapto-6-nitrobenzothiazolyl diphenyltin chloride with 2-ethoxyl-6-nitrobenzothiazole

The new organotin compound, Ph₂Sn(Cl)[S(C₇H ₃N₂O₂S)]·[(C₇H ₃N₂O₂S)OEt], assembled by an intermolecular aromatic benzothiazole-benzothiazole π-π stacking interaction, has been synthesized by the reaction of diphenyltin dichloride with 2-mercapto-6- nitrobenzothiazole. The title compound was characterized by elemental, IR, ¹H NMR, and X-ray crystallography analyses. Single-crystal X-ray diffraction data reveals that the title compound has two different molecular components. The component Ph₂Sn(Cl)[S(C₇H ₃N₂O₂S)] has a pentacoordinate tin, which further forms an infinite one-dimensional chain by intermolecular non-bonded Cl...S interactions, resulting in an intercalation lattice that holds (C₇H₃N₂O₂S)OEt molecules. The formation of the molecule (C₇H₃N₂O ₂S)OEt as well as its intercalated mechanism has also been discussed.
