Stabilizing, non-covalent interactions in the solid state structure of novel aryltin hydrides and halogenides

A group of novel aryltin chlorides, bromides and hydrides (ArnSnY4-n) (Ar = o-tolyl, 2,6-xylyl, 1-naphthyl, 2-naphthyl, p-n-butylphenyl; Y = Cl, Br, H) have been synthesized and structurally characterized via X-ray diffraction. These compounds display noncovalent intermolecular interactions in the form of edge to face, π–π stacking and C–H···π interactions resulting in discrete arrangements in the solid state. The strength of these interactions and their effect on resulting structural parameters, as well as the consequence of the aromatic substituent on the type of interactions present, will be highlighted and discussed.
