3-(2,4,6-Trimethyl-benzo-yl)-2-naphthoic acid.

ABSTRACT: The asymmetric unit of the title compound, C(21)H(18)O(3), contains two crystallographically independent mol-ecules. The two mol-ecules are linked into cyclic centrosymmetric dimers R(2) (2)(8) by O-H?O hydrogen bonds. The dihedral angles between the naphthalene ring system and the benzene ring are 87.0?(8) and 84.4?(2)° in the two mol-ecules. The crystal packing is stabilized by O-H?O, C-H?? and ?-? inter-actions [centroid-centroid distance = 3.664?(11)?Å]. In one mol-ecule, the mesityl ring is disordered over two positions [occupancy ratio 0.690?(3):0.690?(3)].

The asymmetric unit of the title compound, C(21)H(18)O(3), contains two crystallographically independent mol-ecules. The two mol-ecules are linked into cyclic centrosymmetric dimers R(2) (2)(8) by O-H⋯O hydrogen bonds. The dihedral angles between the naphthalene ring system and the benzene ring are 87.0 (8) and 84.4 (2)° in the two mol-ecules. The crystal packing is stabilized by O-H⋯O, C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.664 (11) Å]. In one mol-ecule, the mesityl ring is  ...[more]
