(4-tert-Butylphenyl)acetic acid
In the title compound, C(12)H(16)O(2), the plane of the carboxylic acid group is almost perpendicular to the benzene ring [dihedral angle 80.9 (3)°] and the tert-butyl unit is disordered over two sets of sites in a 0.503 (6):0.497 (6) ratio. In the crystal structure, centrosymmetric dimers arise from pairs of O-H⋯O hydrogen bonds involving the carboxylic acid groups.
متن کامل4-tert-Butylamino-3-nitrobenzoic acid
In the title compound, C(11)H(14)N(2)O(4), all non-H atoms lie in a mirror plane except for one of the methyl groups which deviates from the mirror plane by 0.919 (3) Å and is twisted by a torsion angle of 62.9 (2)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal packing, the mol-ecules are linked together by O-H⋯O hydrogen bonds, forming dimers with graph-s...
متن کامل1-(tert-Butoxycarbonyl)piperidine-4-carboxylic acid
In the title compound, C(11)H(19)NO(4), the piperidine ring adopts a chair conformation. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, forming a layer parallel to the bc plane.
متن کاملRacemic 4-(4-tert-butylphenyl)-2,6-dimethylcyclohex-3-enecarboxylic acid
The chirality of the title compound, C(19)H(26)O(2), is solely generated by the presence of the double bond in the cyclo-hexene ring. This compound was synthesized to study the inter-action of the two enanti-omers in the solid state. The resultant racemate is made up of carboxylic acid RS dimers. Inter-molecular O-H⋯O hydrogen bonds produce centrosymmetric R(2) (2)(8) rings which dimerize the t...
متن کامل2-[(3,5-Di-tert-butyl-4-hydroxybenzyl)sulfanyl]benzoic acid
In the title compound, C(22)H(28)O(3)S, the dihedral angle between the two aromatic rings is 80.56 (6)°. The hy-droxy group is shielded by the two sterically hindered tert-butyl groups and therefore is not involved in any hydrogen bonding. The C-O-H fragment is coplanar with the aromatic ring, the dihedral angle between them being 7(5)°. In the crystal structure, pairs of mol-ecules are hydroge...
