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

ABSTRACT: In the title compound, C(14)H(11)FN(6)S, the 1,2,4-triazolo[3,4-b][1,3,4]thia-diazole ring system is essentially planar [maximum deviation = 0.022?(3)?Å] and is inclined at dihedral angles of 15.00?(18) and 52.82?(16)° with respect to the pyrazole and phenyl rings. In the crystal, mol-ecules are linked into two-dimensional networks parallel to (100) via inter-molecular N-H?N and weak C-H?N hydrogen bonds. The crystal packing is further consolidated by weak ?-? stacking inter-actions, with a centroid-centroid distance of 3.590?(2)?Å. The crystal studied was an inversion twin with a 0.37?(13):0.63?(13) domain ratio.

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.

Project description:The crystal structure of the title compound, C(16)H(11)FN(4)OS, was synthesized in the course of our studies on 1,2,4-triazolo[3,4-b][1,3,4]thia-diazo-les as inhibitors of p38 mitogen-activated protein kinase (MAPK).
