5-(2-Chlorophenyl)-4-phenyl-3,4-dihydro-2H-1,2,4-triazole-3-thione

1-(3,4-Dichlorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethyleneaminoN-methylcarbamate

“…Bond lengths and angles of the triazole rings are in agreement with those in previous reports (Çoruh et al, 2003;Li et al, 2005). The N=C bond length [N4=C7 = 1.285 (4) Å] are close to the value reported in the literature (Puviarasan et al, 1999). Atoms Cl1/Cl2/O1/N4/C7/C8/C11 lies in the benzene ring (C1/C2/C3/C4/C5/C6) plane, and the deviations from the least-squares plane through the ring atoms are all smaller than 0.046 2…”

“…The presence of a substituent on N4 causes a lengthening of the N-N bond length [N3-N4= 1.390 (3) Å] with respect to the corresponding bonds in 5-(2-chlorophenyl)-4-phenyl-3,4-dihydro-2H-1,2,4-triazole-3-thione [N-N= 1.374 (2) Å; Puviarasan et al, 1999] and in 4-methyl-1,2,4-triazole and 1-methyltetrazole [N-N= 1.344 (2) Å; Palmer & Parsons, 1996]. The S-C bond lengths [S21-C22= 1.681 (4)Å and S21-C25= 1.6807 Å] agree with values reported in the literature [S41-C44=1.676 (4)Å and S41-C41=1.689 (3)Å (Vrabel et al, 2005), C14-S1=1.692Å and C11-S1=1.…”

“…The N21═C21 bond length [1.269 (4) Å] agree with values reported in the literature [1.261 (4) Å in the 4-amino-3methtl-1,2,4-triazole-5-thione derivative of p-nitrobenzaldehyde (Liu et al, 1999), 1.267 (2) Å in 4-(4-hydroxybenzylidenamino)-4H-1,2,4-triazole hemihydrate (Zhu et al, 2000) and 1.271 (3) Å in the 1-acetyl-4-(p-chlorobenzylideneamino)-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one (Çoruh et al, 2003)]. The presence of a substituent on N3 causes a lengthening of the N-N bond length [N1-N3= 1.385 (4) Å] with respect to the corresponding bonds in 5-(2-chloro- Puviarasan et al, 1999] and in 4methyl-1,2,4-triazole and 1-methyltetrazole [N-N= 1.344 (2) Å; Palmer & Parsons, 1996]. The S-C bond lengths [S11 -C12= 1.692 (6) Å and S11-C15= 1.685 (5) Å] agree with value reported in the literature (Vrábel et al, 2005;Yılmaz et al, 2006)].…”
