A facile synthesis and comparative structural characterization with DFT, fluorescence behavior, and anti-microbial activity of <i>O</i>,<i>O'</i>-diethyl-<i>S</i>-(<i>N</i>-phthalimidomethyl) dithiophosphate

O,O'-Diethyl-S-(N-phthalimidomethyl) dithiophosphate was synthesized and characterized by different spectroscopic methods (UV, IR, 1H, 13C, 31P, and 15N NMR) as well as DTA, TGA, DSC, and ESI techniques and single crystal X-ray diffraction. The compound exhibits fluorescence behavior and can serve as an antimicrobial agent. The crystal structure of O,O′-diethyl-S-(N-phthalimidomethyl) dithiophosphate displays the monodentate nature of the alkyl dithiophosphate moiety.
