O,O′-2-Iodo-1,3-phenyl­ene bis­(diphenyl­phosphinothio­ate)

The title compound, C(30)H(23)IO(2)P(2)S(2), was synthesized by the reaction of 2-iodo­benzene-1,3-diol, chloro­diphenyl­phosphine, Et(3)N and sulfur. The P=S bonds project to opposite sides of the central aromatic ring. The O—P—S and C—P—S bond angles are significantly larger than the O—P—C and C—P...

Sumario:The title compound, C(30)H(23)IO(2)P(2)S(2), was synthesized by the reaction of 2-iodo­benzene-1,3-diol, chloro­diphenyl­phosphine, Et(3)N and sulfur. The P=S bonds project to opposite sides of the central aromatic ring. The O—P—S and C—P—S bond angles are significantly larger than the O—P—C and C—P—C bond angles, indicating significant distortion of the tetra­hedral geometries of the P atoms. The P=S bond lengths of 1.9311 (13) and 1.9302 (12) Å in the title compound are shorter than that found in Ph(3)P=S [1.950 (3) Å] because the replacement of one C atom attached the P atom by an O atom increases the effective electronegativity of the P atom.
