By Vitaly A. Osyanin, Elena A. Ivleva, Victor B. Rybakov and Yurij N. Klimochkin


The asymmetric unit of the title compound, C14H13O2PS2, contains two crystallographically independent mol­ecules, which differ in the conformation of the 1,3,2-benzoxathia­phosphinine moieties (screw boat in the first mol­ecule and envelope in the second mol­ecule). In the crystal, neither classical nor non-classical hydrogen bonds are found. Weak inter­actions (about 2.9–3.0 Å) between the lone pair of the terminal S atoms with H atoms occur. This compound was further characterized by 1H NMR and IR spectroscopy
