Abstract :1,2-Ethylene-bisinsert ignore into journalissuearticles values(para-methyl pyridinium); dichromate, insert ignore into journalissuearticles values(C$_{14}$H$_{18}$N$_{2});$[Cr$_{2}$O$_{7}$], is used as a new oxidizing agent in conversion of some alcohols to their corresponding carbonyl compounds in CH$_{3}$CN solvent and also under solvent-free conditions. In both procedures, high conversion percentages are observed. However, a much shorter reaction time is achieved in solvent-free conditions. For allylic alcohols, the C=C bond is not oxidized and the examined saturated alcohol in this work insert ignore into journalissuearticles values(i.e. cyclo-hexanol); remains intact, which illustrates the mild nature of reagent used. The structure of the reagent is investigated by single-crystal X-ray diffraction analysis. The C--H$\cdots$O and O$\cdots \pi$ interactions are the most important features of crystal packing, which are visualized by the Hirshfeld surface map.
