General Description

Tetra-p-tolylsilane is a chemical compound with the molecular formula C28H28Si. It is a silane compound, which means it contains a silicon atom bonded to hydrogen atoms and organic groups. Tetra-p-tolylsilane is often used as a precursor in the synthesis of various organosilicon compounds. It is also used in the production of silicone polymers and resins, as well as in the manufacturing of electronic materials and coatings. Tetra-p-tolylsilane is a colorless liquid with a molecular weight of 392.61 g/mol, and it has a melting point of -30 °C and a boiling point of 82-83 °C. It should be handled with care as it is flammable and may cause skin and eye irritation upon contact.

Central-atom size effects on the methyl torsions of group XIV tetratolyls

The Group XIV tetratolyl series X(C6H4-CH 3)4 (X=C, Si, Ge, Sn, Pb) were studied by using inelastic neutron scattering to measure the low-energy phonon spectra to directly access the methyl-group torsional modes. The effect of increased molecular radius as a function of the size of the central atom was shown to have direct influence on the methyl dynamics, reinforced with the findings of molecular dynamics and contact surface calculations, based upon the solid-state structures. The torsional modes in the lightest analogue were found to be predominantly intramolecular: the Si and Ge analogues have a high degree of intermolecular methyl-methyl group interactions, whilst the heaviest analogues (Sn and Pb) showed pronounced intermolecular methyl interactions with the whole phonon bath of the lattice modes. Size matters! The size of the central atom in the Group XIV tetratolyls was shown to determine the solid-state structures courtesy of the effect that it has on the overall size of the molecules (see figure). Because the outer-most methyl groups enter into close intermolecular interactions (for the Si and Ge analogues), the structure is driven to lower symmetry; as a consequence, the smallest (C) and largest (Sn and Pb) analogues are isostructural.
