Treatment of KS2P(OC6H4)2 (1) with five n-alkyl halides afforded the stable n-alkyldithiophosphate compounds RS2P(OC6H4)2 (26). Single crystal X-ray analysis revealed that the PS2 fragment in 1 displays an isobidentate coordination pattern; compounds 24 display a monodentate binding pattern. The crystal packing of title compounds is stabilized by cation-?, weak hydrogen bonding CH---O, as well as aromatic non-bonded interactions.
