The ammonium salts [Et3NH]L-+(-){L- = [(SPMe2)(SPPh2)N](-) (1), Ph2PS2- (2)} were obtained in the reaction between triethylamine and the corresponding organophosphorus acid in a 1: 1 molar ratio, while [2-{O(CH2CH2)(2)N(H)CH2}C6H4](+)[S2P(OPri)(2)](-) (3) resulted as hydrolysis product in the process of growing crystals of [2-{O(CH2CH2)(2)N(H)CH2}C6H4SeS2P(OPri)(2). Compounds 1 and 2 were characterized by H-1 and P-31 NMR spectroscopy. Single-crystal X-ray diffraction studies revealed the presence of short intermolecular S center dot center dot center dot H contacts which result in the formation of dimeric units in 1 and of a layered supramolecular structure in 3.
