Abstract

In the title salt, C14H14NO+·C24H20B−·C2H6OS, the cation is nearly planar and is totally disordered, each of the two positions being occupied equally. The crystal structure has an O—H⋯O hydrogen bond between the disordered cation and the dimeth­yl sulfoxide mol­ecule. A C—H⋯π inter­action between the disordered cation and a phen­yl ring of the tetra­phenyl­borate anion is also present. [ABSTRACT FROM AUTHOR]

Abstract

In the cation of the title compound, C20H26N22+·2Cl−·CH4O, there is an approximate twofold rotation axis. All the four chiral centers are in the S configuration. All three six-membered rings in the central part of the cation adopt a boat conformation. Both chloride anions and the O atom in the solvent mol­ecule form hydrogen bonds with the cation, resulting in a chain along [010]. [ABSTRACT FROM AUTHOR]
