Abstract

The crystal structure of a biologically active (E)-1-[(2-chloro-1,3-thiazol-5-yl)methyl)]-3-methyl-2-nitroguanidine with molecular formula C6H8N5O2ClS has been investigated based on the molecular conformation and the supramolecular packing in terms of intermolecular interactions involving N–H⋯O, N–H⋯N, and C–H⋯O–N (nitro group), C–H⋯N (thiazol) hydrogen bonds, offset π–π stacking, C–H⋯π and N(–NO2)⋯C=N intermolecular interactions. Furthermore, a short C–Cl⋯O–N contact is also present which contributes towards the crystal packing. The lattice energy of the title compound has been calculated using the PIXEL approach (the Coulomb-London-Pauli (CLP) model) and compared with periodic calculations performed using CRYSTAL09. In addition, Hirshfeld surface analysis and fingerprint plots provide a platform for the evaluation of the contribution of different intermolecular interactions towards the packing behaviour.
