Reaction of N-bromosuccinimide with ammonium salt of alkylene (dialkyl) dithiophosphates, [OGOPS2NH4; G=–CMe2CMe2–CH2CMe2CH2–, CMe2CH2CHMe2–, CH2CH2CHMe2–; (RO)2PS2NH4; R=C2H5, n–C3H7, i–C3H7], in 1: 1 molor ratio in refluxing benzene solution yields red/brown-colored sticky liquids. These newly synthesized complexes have been characterised by physicochemical and spectroscopic techniques (MW, IR, NMR [H1 and P31]). The computational semiempirical calculations (MOPAC6P/c) have also been studied for these complexes. On the basis of the above studies, the formation of P–S–N chemical linkage has been established.
