Abstract:
In the title compound, C(22)H(19)N(2) (+)·ClO(4) (-), the three pendant aromatic rings are twisted from the plane of the imidazolium ring by dihedral angles of 17.3 (2), 65.7 (2) and 3.4 (2)°. In the crystal structure, N-H⋯O and N-H⋯(O,O) hydrogen bonds link the ions, forming a ribbon-like structure along the a axis.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
