Probing the relationships between molecular conformation and intermolecular contacts in N,N-dibenzyl-N '-(furan-2-carbonyl)thiourea

Abstract

In the crystal structure of the title compound, C20H18N2O2S, molecules are linked by bifurcated C-H center dot center dot center dot O hydrogen-bond interactions, giving rise to chains whose links are composed of alternating centrosymmetrically disposed pairs of molecules and characterized by R-2(2)(10) and R-2(2)(20) hydrogen-bonding motifs. Also, N-H center dot center dot center dot S hydrogen bonds form infinite zigzag chains along the [010] direction, which exhibit the C(4) motif. Hirshfeld surface and fingerprint plots were used to explore the intermolecular interactions in the crystal structure. This analysis confirms the important role of C-H center dot center dot center dot O hydrogen bonds in the molecular conformation and in the crystal structure, providing a potentially useful tool for a full understanding of the intermolecular interactions in acylthiourea derivatives.
