O,O-Bis(2-Tert-Butylphenyl) Chlorothiophosphonate

Abstract

The title compound, C<inf>20</inf>H<inf>26</inf>ClO<inf>2</inf>PS, displays distorted tetrahedral geometry around the P atom, which lies on a crystallographic twofold axis. The S and Cl substituents on the P atom are disordered about the twofold axis. The internal angles in the aromatic rings vary significantly due to the steric influence of the tert-butyl groups. Weak intramolecular C-H⋯O hydrogen bonds generate two S(6) motifs. The crystal structure is stabilized only by van der Waals interactions. © 2007 International Union of Crystallography All rights reserved.
