4-[(Benzyl­amino)­carbon­yl]-1-methyl­pyridinium halogenide salts: X-ray diffraction study and Hirshfeld surface analysis

Two salts of 4-[(benzyl­amino)­carbon­yl]-1-methyl­pyridinium (Am) with chloride (C(14)H(15)N(2)O(+)·Cl(−)) and bromide (C(14)H(15)N(2)O(+)·Br(−)) anions were studied and compared with the iodide salt. AmCl crystallizes in the centrosymmetric space group P2(1)/n while AmBr and AmI form crystals in t...

Sumario:Two salts of 4-[(benzyl­amino)­carbon­yl]-1-methyl­pyridinium (Am) with chloride (C(14)H(15)N(2)O(+)·Cl(−)) and bromide (C(14)H(15)N(2)O(+)·Br(−)) anions were studied and compared with the iodide salt. AmCl crystallizes in the centrosymmetric space group P2(1)/n while AmBr and AmI form crystals in the Sohncke space group P2(1)2(1)2(1). Crystals of AmBr are isostructural to those of AmI. The cation and anion are bound by an N–H⋯Hal hydrogen bond. Hirshfeld surface analysis was used to compare different types of inter­molecular inter­actions in the three structures under study.
