Unsymmetrically Substituted Thioureas. 1,1-Dimethyl-3-o-tolylthiourea and 1,1-Diethyl-3-o-tolylthiourea

1-(2-Bromo-4-chlorophenyl)-3,3-dimethylthiourea

“…In (I) ( Fig. 1), all bond lengths and angles are normal and correspond well to those observed in the related compounds (Zhao et al, 2008;Ramnathan et al, 1996). The non-hydrogen atoms in (I) fall into two planes with an interplaner angle of 54.38 6…”

N-Phenyl-4-morpholinecarbothioamide and N-(2-Tolyl)-4-morpholinecarbothioamide

“…The lone N--H group present in the molecules of (1) and (2) is involved in N--H...S hydrogen bonding to neighbouring molecules forming chains that run parallel to a crystallographic axis. Our structural studies on substituted thiourea derivatives reveal that the formation of one-dimensional chains is associated with an axial length of ca 8 * (two molecules as repeat unit) along which the chains run: 7.912A in 1-dimethyl-3-tolylthiourea (Ramnathan et al, 1996), 8.488,~ in 1-diethyl-3-tolylthiourea (Ramnathan …”

Crystal structures of three N,N,N′-trisubstituted thioureas for reactivity-controlled nanocrystal synthesis

“…The structures with refcodes HIFTIX and HIFTOF are two unsymmetrical thiourea derivatives, 1,1-dimethyl-3-o-tolylthiourea and 1,1-diethyl-3-o-tolylthiourea (Ramnathan et al, 1996), containing o-tolyl groups as secondary amine substituents, while KUFQOS (Zhao et al, 2008), KUFQOS01 (Panda et al, 2017) and KUFQOS02 (Bhide et al, 2021) represent the same structure of 1,1-dimethyl-3-phenylthiourea. Halogen-substituted phenyl rings as secondary amine substituents are found for refcodes POFJUR and QEMZOA, 4 of 7 Dhaene et al C 22 H 22 N 2 S, C 14 H 14 N 2 S and C 15 H 24 N 2 S Acta Cryst.…”
