Researchers successfully synthesized two new types of Sb(III) and Sb(V) peri-substituted acenaphthene phosphorus-antimony compounds. The Sb(III) compound, 1, was prepared by reacting the organolithium precursor with dichloro(p-tolyl)stibine, and 2 was prepared by chlorination of 1. Both compounds were characterized by multinuclear (H-1, C-13, and P-31) NMR spectroscopy and their molecular structures were resolved by single-crystal X-ray diffraction. Both compounds exhibit a dative P-Sb interaction with antimony serving as the Lewis acidic acceptor group.

Both 1 and 2 were characterized by multinuclear (H-1, C-13 and P-31) NMR spectroscopy, and their molecular structures resolved by single-crystal X-ray diffraction. Both compounds show a dative P-Sb interaction with the antimony being the acceptor group in both cases owing to its Lewis acidity.
