Crystallographic Studies on Non-Covalent Interactions in Aryl-Substituted Antimony Organometallics

A series of novel and previously published organoantimony compounds (RnSbX3−n, X = Cl, Br; R = o-tolyl, 2,6-xylyl, 1-naphthyl, and 9-anthracenyl), were synthesized and characterized. In addition, single-crystal X-ray diffraction was employed to elucidate the molecular structures of all solid species. These compounds display non-covalent intermolecular interactions in the form of edge-to-face, π···π stacking, and CH3···π interactions, and the effects of the substituent type and substituent bulk on the nature of these interactions present will be highlighted and discussed.
