4-(4-Chloro-phen-yl)-1-[3-(4-fluoro-benzo-yl)prop-yl]-4-hydroxy-piperidin-1-ium 2,4,6-trinitro-phenolate (haloperidol
Abstract:
In the title salt, C(21)H(24)ClFNO(2) (+)·C(6)H(2)N(3)O(7) (-), the dihedral angle between the aromatic rings in the cation is 16.5 (1)°. The piperidium ring adopts a slightly distorted chair conformation. Strong hydrogen-bonding inter-actions occur between the N-H and O-H functions of the 4-hydroxy-piperidin-1-ium ring and the phenolate and p-NO(2) O atoms of the picrate anion. In addition, a variety of weak C-H⋯O and π-π ring inter-actions between cations and cation-anion neighbors [centroid-centroid distances = 3.597 (1) and 3.848 (10) Å] further consolidate the packing.

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...
