5-Chloro-1H-indole-3-carb-oxy-lic acid.

ABSTRACT: In the title compound, C(9)H(6)ClNO(2), the carboxyl group is twisted from the indole ring system by 9.00?(8)°. In the crystal, inversion dimers linked by pairs of O-H?O hydrogen bonds generate R(2) (2)(8) loops and N-H?O hydrogen bonds link the dimers into (001) sheets. Aromatic ?-? stacking inter-actions [centroid-centroid distance = 3.7185?(12)?A °] are also observed.

In the title compound, C(9)H(6)ClNO(2), the carboxyl group is twisted from the indole ring system by 9.00 (8)°. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops and N-H⋯O hydrogen bonds link the dimers into (001) sheets. Aromatic π-π stacking inter-actions [centroid-centroid distance = 3.7185 (12) A °] are also observed. ...[more]

6-Fluoro-1H-indole-3-carb-oxy-lic acid.

Project description:In the title compound, C(9)H(6)FNO(2), all the non-H atoms are approximately coplanar, the carb-oxy O atoms deviating by 0.0809 and -0.1279?Å from the indole plane. In the crystal, O-H?O hydrogen bonds link the mol-ecules into dimers which are linked via N-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance = 3.680?(2)?Å].

(1H-Benzimidazole-5-carb-oxy-lic acid-κN)(1H-benzimidazole-6-carb-oxy-lic acid-κN)silver(I) perchlorate.

Project description:The reaction of 1H-benzimidazole-5-carb-oxy-lic acid with silver nitrate in the presence of perchloric acid under hydro-thermal conditions yielded the title complex, [Ag(C(8)H(6)N(2)O(2))(2)]ClO(4), which comprises of an [Ag(C(8)H(6)N(2)O(2))(2)] mononuclear cation and a perchlorate anion. The Ag(I) ion is coordinated by two N atoms from two different neutral 1H-benzimidazole-5-carb-oxy-lic acid ligands with an N-Ag-N bond angle of 163.21 (14)°, forming an [Ag(C(8)H(6)N(2)O(2))(2)] mononuclear cation. Although both ligands in the mononuclear cation are monodentate with one N atom coordinated to the metal ion, they are different: one is N(3) coordinated to the Ag (I) ion and the N(1) atom protonated, the other with the N(1) coordinated to the Ag (I) ion and the N(3) atom protonated (and thus formally a 1H-benzimidazole-6-carb-oxy-lic acid rather than a 1H-benzimidazole-5-carb-oxy-lic acid ligand). The planes of the two planar ligands are roughly perpendicular, making a dihedral angle of 84.97 (2)°. The packing of the ions is stablized by extensive O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, and by remote Ag⋯O inter-actions [3.002 (3), 3.581 (5) and 3.674 (5) Å].

1-Cyclo-hexyl-5-(4-meth-oxy-phen-yl)-1H-pyrazole-4-carb-oxy-lic acid.

Project description:In the title compound, C(17)H(20)N(2)O(3), the meth-oxy-phenyl unit is disordered over two sets of sites in a 0.715?(4):0.285?(4) ratio.
