Structure and spectroscopic properties of N,S-coordinating 2-methylsulfanyl-N-[(1H-pyrrol-2-yl)methylidenelaniline methanol monosolvate

Abstract

The reaction of pyrrole-2-carboxaldehyde and 2-(methylsulfanyl)aniline in refluxing methanol gave an olive-green residue in which yellow crystals of the title compound, C12H12N2S center dot CH3OH, were grown from slow evaporation of methanol at 263 K. In the crystal, hydrogen -bonding interactions link the aniline molecule and a nearby methanol solvent molecule. These units are linked by a pair of weak C-H center dot center dot center dot O-methanol interactions, forming inversion dimers consisting of two main molecules and two solvent molecules.
