Structure cristalline, caractérisation spectroscopique, calcul DFT et analyse de surface Hirshfeld du perchlorate de p-toluidinium

The synthesis of p-toluidinium perchlorate (systematic name: 4-methyl­anilinium perchlorate), C(7)H(10)N(+)·ClO(4) (−), was carried out from an aqueous reaction of perchloric acid with p-toluidine. This compound was characterized by powder XRD, IR and UV–Vis spectroscopy. The structure was further c...

description The synthesis of p-toluidinium perchlorate (systematic name: 4-methyl­anilinium perchlorate), C(7)H(10)N(+)·ClO(4) (−), was carried out from an aqueous reaction of perchloric acid with p-toluidine. This compound was characterized by powder XRD, IR and UV–Vis spectroscopy. The structure was further confirmed by a single-crystal X-ray diffraction study. The crystal structure is formed by a succession of two-dimensional mol­ecular layers consisting of perchlorate anions and organic cations parallel to the (100) plane and located at x = 2n + ½ (n ∈ Z). Each mixed layer is formed by infinite chains {C(7)H(10)N(+)·ClO(4) (−)}(n) parallel to the [010] direction and developing along the c axis, generating R (2) (4)(8), R (2) (2)(4) and R (4) (4)(12) graph-set motifs. The results of a theoretical study using the DFT method at the B3LYP/6–311++G(d,p) level are in good agreement with the experimental data. Hirshfeld surface and fingerprint plots reveal that the structure is dominated by O⋯H/H⋯O (54.2%), H⋯H (26.9%) and C—H ⋯π (14.3%) contacts. The studied crystal was refined as a two-component twin
