The title mononuclear complex, [Ni(C7H3NO4)(C9H10N2)3], shows a central NiII atom which is coordinated by two carboxyl­ate O atoms and the N atom from a pyridine-2,6-dicarboxyl­ate ligand and by three N atoms from different 5,6-dimethyl-1H-­benzimidazole ligands in a distorted octa­hedral geometry. The crystal structure shows intermolecular N—H...O hydrogen bonds.

In the title complex, [Ni(C7H3NO4)(C7H6N2)3], the NiII ion is coordinated by two carboxyl­ate O atoms and the N atom from a pyridine-2,6-dicarboxyl­ate ligand and by three N atoms from three benzimidazole ligands to form a slightly distorted octa­hedral geometry. In the crystal, mol­ecules are linked by N—H...O hydrogen bonds to form a three-dimensional network.

The reaction between methyl (R)-2-(2-chloro­phen­yl)-2-hy­droxy­acetate and 3-nitro­benzene­sulfonyl chloride gave the title compound, C15H12ClNO7S, which is a promising inter­mediate for the synthesis of Clopidrogel, an anti­platelet drug used in the prevention of strokes and heart attacks. In the crystal, mol­ecules are linked through C—H...O interactions, and there is also a short Cl...O contact present [Cl...O = 3.018 (2) Å].
