The crystal structure and the absolute configuration of the title comp
ound has been determined from single-crystal X-ray diffraction data. T
he monoclinic unit cell (space group P2(1)) with a = 11.514(2), b = 8.
288(1), c = 13.749(2) angstrom, beta = 99.69(1)-degree and Z = 4 conta
ins two crystallographically independent molecules. The configuration
at the sulfur atom in both molecules is S. A large liability of the me
thoxysulfinylacetic group conformation and configuration is observed.
The conformations and S - C(sp3) - C(sp2)(phen)) bond angles of this g
roup in two independent molecules are distinctly different. The compar
ison of the investigated compound with the literature data of related
molecules is given.
