6-(2-Methyl-phen-yl)-3-(3,4,5-trimethoxy-phen-yl)-1,2,4-triazolo[3,4-b][1,3,4]thia-diazole.

ABSTRACT: In the mol-ecule of the title compound, C(19)H(18)N(4)O(3)S, the planar central heterocylic ring system is oriented with respect to the trimethoxy-phenyl and 2-methyl-phenyl rings at dihedral angles of 4.43?(3) and 4.32?(3)°, respectively. The dihedral angle between the two benzene rings is 7.65?(4)°. In the crystal structure, inter-molecular C-H?N hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(18) dimers. These dimers are connected via a C-H?? contact between the 2-methyl-phenyl and trimethoxy-phenyl rings, and a ?-? contact between the thia-diazole and trimethoxy-phenyl rings [interplanar distance 3.51?Å, dihedral angles 4.17(4)°]. An intramolecular C-H?N hydrogen bond is also present.

6-(Adamantan-1-yl)-3-(3-fluoro-phen-yl)-1,2,4-triazolo[3,4-b][1,3,4]thia-diazole.

Project description:The title mol-ecule, C(19)H(19)FN(4)S, displays C(s) mol-ecular symmetry, in which the crystallographic mirror plane bis-ects the adamantan-1-yl unit while the 3-fluoro-phenyl triazole ring is located on the mirror plane.

In the crystal, ?-? inter-actions between the triazole and phenyl rings occur [centroid-centroid distance = 3.5849?(7)?Å] and weak C-H?F inter-actions form a ribbon propagating in [010].
