Abstract
The observed global conformation of the title compound, C23H21N4OS+.C7 H7O3S(-), is common for 2-acylaminomethyl derivatives of benzodiazepin e. This conformation is stabilized by two hydrogen bonds from the p-to luenesulfonate anion, one from the protonated basic N atom of the hept adiene ring and another from the amidic N atom in the side chain. The thienyl ring exhibits 180 degrees rotational disorder.
