Abstract

IN THE TITLE COMPOUND [SYSTEMATIC NAME: (tert-butyl-dimethyl-silyl)methane-triyl tris-(4-methyl-benzene-sulfonate)], C(32)H(44)O(10)S(3)Si, the central C atom and the Si(IV) center are in a tetra-hedral configuration. The inter-planar angles between pairs of the three benzene rings of the 4-methyl-phenyl-sulfonyl units are 41.15 (10), 18.11 (10) and 44.09 (10)°. C-H⋯π inter-actions are observed in the crystal structure. Mol-ecules are linked into screw chains along the b axis by weak C-H⋯O inter-actions. Weak intramolecular C-H⋯O hydrogen bonds are also present.
