X-ray study of 2-(3,5-dimethylpyrazolyl)-1,3-benzothiazole

Crystal and molecular structure of (Z)-2-(1,3-benzothiazol-2-yl)-2-(6,7,8,9-tetrahydro-5H-benzocyclohepten-5-ylidene)ethanonitrile

“…Bhatia et al, 1991). Moreover, the bond angle C(6)--S--C(7) of 89.2(1) ~ is similar to that observed in related substituted thiazole derivatives (Ruben et al, Table 3.…”

“…1.378(3) C15--C16 1.366(2) C5--C6 1.396(2) C16--C17 1.380(2) C6--C8 1.468(2) C17--C18 1.389(2) C8--C9 1.347(2) C18--C19 1.386 (2) 1974, Laurent et al, 1981, Bhatia et al 1991. The cyano group is slightly inclined with respect to the mean benzothiazole ring.…”

Crystal and molecular structure of 2-(1,3-benzothiazol-2-yl)-2-(4-tert-butylcyclohexylidene)ethanonitrile

“…1 shows the molecular geometry and the labeling scheme. The geometrical features of the benzothiazole in the title compound compare well with those reported in 2-(3,5-dimethylpyrazolyl)-l,3-benzothiazole (Bhatia et al, 1991). The average bond length of the benzene ring is 1.385(6).~ and the average bond angle is 120.0~ which are in agreement with the standard values.…”

Diethyl [4-(1,3-benzothiazol-2-yl)benzyl]phosphonate

“…In (I), the bond lengths and angles are normal and comparable with those observed in the related compound (Bhatia et al, 1991). The benzene ring and the benzothiazole mean plane are almost coplanar forming a dihedral angle of 2.29 (2)°.…”
