1-[(2,4-Dichlorobenzoyl)methyl]-4-(N,N-dimethylamino)pyridinium bromide

Abstract

In the title compound, C15H15Cl2N2O+·Br−, the angle between the least‐squares planes of the di­chloro­phenyl moiety and the pyridine ring is 20.23 (9)°. The molecular packing is mainly influenced by intermolecular C—H⋯Br hydrogen‐bond interactions. The mol­ecules form an extended chain along the b axis, through C—H⋯Br hydrogen bonds.

4-Amino-(1-methylphenyl)pyridinium bromide

“…1. The bond lengths and angles within the pyridinium ring are normal and comparable with those reported for related structures (Sundar et al, 2004a(Sundar et al, ,b, 2005(Sundar et al, , 2006(Sundar et al, , 2006a. In (I), the dihedral angle between the planes of the pyridine and benzene rings is 80.0 (1) .…”

1-[2-(Biphenyl-4-yl)-2-oxoethyl]-4-(N,N-dimethylamino)pyridinium bromide hemihydrate

“…1). The bond lengths and angles in the DMAP moieties of A and B (Table 1) are comparable with those reported for related structures (Sundar et al, 2004). The angles between the least-squares planes of the dimethylamino moiety and the pyridine ring in cations A and B are 10.6 (2) and 13.3 (2) , respectively.…”

“…The dihedral angles between the mean planes of the benzene rings in A and B are 15.7 (2) and 1.5 (2) , respectively. In cation A, the angle between the leastsquares planes of the pyridine ring and biphenyl moiety is 50.2 (1) , whereas in cation B, the corresponding angle is 86.34 (12) , close to the values of 81.01 (11) and 78.64 (13) observed in related structures (Sundar et al, 2004).

“…4-Dimethylaminopyridine (DMAP) is a well known catalyst for a variety of synthetic transformations under mild conditions (Prabakaran et al, 2001, and references therein;Sundar et al, 2004). In a continuation of the identification of bioactive compounds, the structure determination of the title compound, (I), was undertaken.…”

Synthesis, intermolecular interactions and biological activities of two new organic–inorganic hybrids C6H10N2,2Br and C6H10N2,2Cl·H2O

“…1 Weak intermolecular interactions which are important in the elds of physical, chemical and life sciences represent the backbone of self-assembly processes and supramolecular architectures and exert directional and saturation effects. [2][3][4][5] The hydrogen bond, which is the most common among weak interactions, remains the most important and reliable means of enforcing molecular organization in the solidstate, [6][7][8][9][10][11][12][13] plays a critical role in many chemical and biological processes, and has been a subject of research interest. [14][15][16] To enrich the varieties in such kinds of hybrid compounds and to investigate the inuence of hydrogen bonds on the structural features, we aimed to use the amine 2-(aminomethyl)pyridine (amp) also commonly known as 2-picolylamine (pic) a clear yellowish liquid used as an intermediate in the pharmaceutical industry [17][18][19][20][21] for obtaining two new amine halide salts C 6 H 10 N 2 ,2Br and C 6 H 10 N 2 ,2Cl$H 2 O which are expected to possess notable chemical and biological activities.…”
