Abstract

Triethylammonium salts of O,O′-alkylene dithiophosphato like OGOPS2HNEt3, [where, G = –CH2CMe2CH2–(1), –CH2CEt2CH2–(2), –CMe2CH2CHMe–(3) and –CMe2CMe2–(4)] have been synthesized in quantitative yield by the direct reaction of P2S5 with 1,2- and 1,3-substituted glycols in presence of triethylamine, Et3N, in 1:2:2 molar stoichiometry in toluene. These have been mainly characterized by molecular weight, IR and NMR (1H, 13C and 31P) spectroscopic studies. Single crystal X-ray structure analysis of [OCH2CMe2CH2OPS2HNEt3] reveals that phosphorus atom is tetrahedrally bonded to two sulfur atoms and two oxygen atoms in the ring and the molecule exists as discrete cation and anion. The structure is stabilized by cation–anion N–H···S hydrogen bonded interactions. Antiparallel pattern of triethylammonium ion is sandwiched within the two-dimensional layers of the ring system.
