4-(Dimethylamino)benzaldehyde 4-ethylthiosemicarbazone

Abstract

Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.001 Å; disorder in main residue; R factor = 0.041; wR factor = 0.119; data-to-parameter ratio = 38.8.The title thiosemicarbazone derivative, C 12 H 18 N 4 S, features intramolecular N-HÁ Á ÁN and C-HÁ Á ÁS hydrogen bonds which generate S(5) ring motifs. The dihedral angle between the benzene ring and the thiourea unit is 6.30 (6) indicating planarity in the molecule. Intermolecular N-HÁ Á ÁS hydrogen bonds generate dimers with an R 2 2 (8) ring motif. The methyl group of the N-ethyl residue is disordered and was refined with site occupancies of 0.521 (5) and 0.479 (5). Related literature

“…The ionophore 4-(dimethyl-amino)benzaldehyde 4-ethylthiosemicarbazone (DMABET, Figure 1) was prepared according to the literature [25] through dropwise addition of 4-dimethylaminobenzaldehyde to 4-ethyl-3-thio-semicarbazide in ethanol. Yellow crystals were obtained after recrystallization from ethanol.…”
