5-Methyl-1,2-oxazole-3-carb-oxy-lic acid.

ABSTRACT: In the crystal structure of the title compound, C(5)H(5)NO(3), all the non-H atoms are approximately coplanar: the carb-oxy O atoms deviating by 0.013?(2) and -0.075?(2)?Å from the isoxazole ring plane. In the crystal, the molecules form inversion dimers linked by pairs of O-H?O hydrogen bonds and the dimers stack via ?-? inter-actions [centroid-centroid distance = 3.234?(2)?Å].

In the crystal structure of the title compound, C(5)H(5)NO(3), all the non-H atoms are approximately coplanar: the carb-oxy O atoms deviating by 0.013 (2) and -0.075 (2) Å from the isoxazole ring plane. In the crystal, the molecules form inversion dimers linked by pairs of O-H⋯O hydrogen bonds and the dimers stack via π-π inter-actions [centroid-centroid distance = 3.234 (2) Å]. ...[more]

4-Carbamoylpiperidinium 2-carb-oxy-benzoate-benzene-1,2-dicarb-oxy-lic acid (1/1).

Project description:The asymmetric unit of the title salt adduct, C(6)H(13)N(2)O(+)·C(8)H(5)O(4) (-)·C(8)H(6)O(4), comprises one isonipecotamide cation, a hydrogen phthalate anion and a phthalic acid adduct mol-ecule.

(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].

2-Amino-5-chloro-pyridinium 2-carb-oxy-benzoate-benzene-1,2-dicarb-oxy-lic acid (3/1).

Project description:The asymmetric unit of the title compound, 3C(5)H(6)ClN(2) (+)·3C(8)H(5)O(4) (-)·C(8)H(6)O(4), contains three independent 2-amino-5-chloro-pyridinium cations, three independent hydrogen phthal-ate anions and one phthalic acid mol-ecule. In the crystal structure, there are two kinds of supra-molecular tapes. One is formed by two independent cations with two anions through N-H⋯O and C-H⋯O hydrogen bonds. Another one is formed by the other cation and anion, and the phthalic acid mol-ecule via N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. These two tapes are connected by an O-H⋯O hydrogen bond, forming a double-tape structure.
