Crystal structure of 4-azidomethyl-6-tert-butyl-2H-chromen-2-one
In the title compound, C14H15N3O2, one of the methyl C atoms of the tert-butyl group lies almost in the plane of the chromene ring system [deviation = -0.097 (2) Å], one lies above and one lies below [deviations = 1.460 (3) and 1.006 (3) Å, respectively]. The C-C-N-N torsion angle is 142.33 (17)°. In the crystal, moelcules are linked by weak C-H⋯O hydrogen bonds to generate C(6) chains propagat...
متن کاملCrystal structure of 2,4-di-tert-butyl-6-(hydroxymethyl)phenol
The title compound, C15H24O2, is an example of a phenol-based pendant-arm precursor. In the mol-ecule, the phenol hy-droxy group participates in an intra-molecular O-H⋯O hydrogen bond with the pendant alcohol group, forming an S(6) ring. This ring adopts a half-chair conformation. In the crystal, O-H⋯O hydrogen bonds connect mol-ecules related by the 31 screw axes, forming chains along the c ax...
متن کاملCrystal structure of 2-tert-butyl-2,3-dihydro-1H-benzo[c]pyrrol-1-one
The asymmetric unit of the title compound, C12H15NO, comprises two sym-metry-independent mol-ecules which differ mainly in the conformations of the tert-butyl groups. The mol-ecules contain an essentially planar five-membered 3-pyrroline ring incorporating a carbonyl substituent (pyrrolinone) which forms part of an isoindolinone skeleton. The planarity of the pyrrole ring is compared to other s...
متن کاملCrystal structure of 9-butyl-6-[2-(pyridin-4-yl)ethenyl]carbazol-3-amine
The asymmetric unit of the title compound, C23H23N3, consists of two mol-ecules, A and B, with different conformations. In mol-ecule A, the dihedral angle between the carbazole ring system (r.m.s. deviation = 0.028 Å) and the pyridine ring is 20.28 (9)° and the N-C-C-C torsion angle of the butyl side chain is -63.4 (3)°. The equivalent data for mol-ecule B are 0.065 Å, 48.28 (11)° and 61.0 (3)°...
متن کاملCrystal structure of 6-chloro-5-(2-chloroethyl)-3-(propan-2-ylidene)indolin-2-one
The title compound, C13H13Cl2NO, has a 3-(propan-2-yl-idene)indolin-2-one core with a Cl atom and a chloro-ethyl substituent attached to the aromatic ring. Two atoms of the aromatic ring and the chloro-ethyl substituent atoms are disordered over two sets of sites with a refined occupancy ratio of 0.826 (3):0.174 (3). In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, formin...
