Synthesis and crystal structure of (E)-2-benzyl-1,3-diphenylisothiouronium iodide

Abstract

In the title molecular salt, C20H19N2S+·I−, prepared by the reaction of 1,3-diphenylthiourea and benzyl iodide, the C—S—C thioether bond angle is 101.66 (9)° and electrons are delocalized over the N+= C—N skeleton. The dihedral angle between the aromatic rings attached to the N atoms is 40.60 (9)°. In the crystal, N—H...I hydrogen bonds link the components into [100] chains.
