Main group elements do not use their d-orbitals in bonding. Your answer suggests they do. Remember that iodine’s 5d orbitals are even higher in energy than its 6s orbitals, yet nobody suggests 6s should hybridise alongside with 5s and 5p. Think about it. $\endgroup$ –

WebMar 23, 2007 · A series of sulfonium halides bearing allyl groups have been prepared and characterized. Anion metathesis with Li [Tf 2 N] and Ag [N (CN) 2] resulted in sulfonium-based ionic liquids which exhibit low viscosities at room temperature. The solid state structure of one of the halide salts was determined by single crystal X-ray diffraction.
