Crystal structure of 2-[(3aS,6R)-3,3,6-trimethyl-3,3a,4,5,6,7-hexahydro-2H-indazol-2-yl]thiazol-4(5H)-one
The title compound, C13H19N3OS, is a new thia-zolidin-4-one derivative prepared and isolated as the pure (3aS,6R)-diastereisomer from (R)-thio-semicarbazone pulegone. It crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The compound is composed of a hexhydro-indazole ring system (viz. a five-membered di-hydro-pyrazole ring fused to a cyclo-hexyl ring) with a thia-zo...
متن کامل4,7,8-Trimethyl-2H-chromen-2-one
The mol-ecule of the title compound, C(12)H(12)O(2), is essentially planar, with a maximum deviation from the mean plane of all non-H atoms of 0.038 (1) Å for the methyl C atom in the 8-position. The crystal structure is characterized by anti-parallel π-π stacking along the c axis, with centroid-centroid distances as short as 3.866 (1) Å. In the crystal, C-H⋯O hydrogen bonds connect the mol-ecu...
متن کاملCrystal structure of triethyl 2-(5-nitro-2H-indazol-2-yl)propane-1,2,3-tricarboxylate
In the title compound, C19H23N3O8, the 5-nitro-2H-indazol-2-yl unit is almost planar, with the maximum deviation from the mean plane being 0.024 (2) Å. The fused-ring system is nearly perpendicular to the three carboxyl-ate groups, with dihedral angles of 90.0 (3), 83.8 (1) and 80.4 (1)°. The ethyl groups attached to both ends of the propane chain are each disordered over two sets of sites, wit...
متن کامل2-(2H-Indazol-2-yl)-1-phenylethanone
The asymmetric unit of the title compound, C(15)H(12)N(2)O, contains two independent mol-ecules with different conformations, the phenyl ring and indazole mean plane in the two mol-ecules forming dihedral angles of 50.82 (5) and 89.29 (6)°. In the crystal, weak C-H⋯O and C-H⋯N hydrogen bonds and C-H⋯π inter-actions consolidate the packing.
متن کامل1-(Furan-2-yl)-2-(2H-indazol-2-yl)ethanone
The asymmetric unit of the title compound, C13H10N2O2, contains two crystallographically independent mol-ecules (A and B). The indazole ring systems are approximately planar [maximum deviations = 0.0037 (15) and -0.0198 (15) Å], and their mean planes are oriented at 80.10 (5) and 65.97 (4)° with respect to the furan rings in mol-ecules A and B, respectively. In the crystal, pairs of C-H⋯N hydro...
