Triethylammonium (S)-(-)-O-[1-(2-naphthyl)ethyl] (4-methoxyphenyl)- dithiophosphonate

Abstract

The crystal structure of the title compound, C6H 16N+·-C19H18O 2PS2 -, consists of the dithiophosphonate anions and the triethylammonium cations, which are linked by N-H?S hydrogen bonds and weak C-H?O hydrogen bonds. In the anion, the benzene ring is oriented with respect to the naphthalene ring system at a dihedral angle of 24.92 (5)°. In the crystal, weak C-H?? interactions also occur.
