A phosphorylated derivative of 4-nitrobenzaldehyde based on the Pudovik reaction, has been synthesized and characterized by X-ray, IR and NMR ¹H, ³¹P and ¹³C spectroscopy. Single crystal X-ray diffraction showed that crystal is formed by the cation of N-didodecylphosphinoxido-4-nitrobenzyledenetetradecylammonium and the anion of 4-methylbenzenesulfonate in a 1:1 ratio and crystallizes in the triclinic space group P-1. Cations form dimers via N–H⋯O contacts with phosphoryl oxygen.

新型配体N-二十二烷基膦基氧化-4-硝基苄基亚甲基四癸基铵-4-甲基苯磺酸盐的合成及晶体结构

已经基于Pudovik反应合成了4-硝基苯甲醛的磷酸化衍生物，并通过X射线，IR和NMR ¹ H，³¹ P和¹³ C光谱进行了表征。单晶X射线衍射表明，晶体由N-二十二烷基膦基氧化-4-硝基苄基亚甲基四癸基铵的阳离子和4-甲基苯磺酸根的阴离子以1：1的比例形成，并在三斜晶系空间群P-1中结晶。阳离子通过与磷酸氧的N–H = O接触形成二聚体。
