3-Carb-oxy-methyl-1H-indole-4-carb-oxy-lic acid.

ABSTRACT: In the title compound, C(11)H(9)NO(4), the carboxyl group bonded to the six-membered ring lies close to the plane of the 1H-indole ring system [dihedral angle = 13.13?(9)°], whereas the carb-oxy-lic acid group linked to the five-membered ring by a methyl-ene bridge is close to perpendicular [78.85?(9)°]. In the crystal, O-H?O and N-H?O hydrogen bonds link the mol-ecules, generating (110) sheets.

(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].
