[Show abstract][Hide abstract] ABSTRACT: The title compound, [ZnBr2(C11H13N3)], was synthesized by hydrothermal reaction of ZnBr2 and (S)-2-(pyrrolidin-2-yl)-1H-benzimidazole. The ZnII atom has a distorted tetrahedral geometry and is coordinated by two N atoms from the chelating organic ligand and two terminal Br− anions. In the crystal structure, molecules are linked into a chain along the  direction by N—H...Br and C—H...Br hydrogen bonds.
[Show abstract][Hide abstract] ABSTRACT: The title compound, C9H10N2O4·H2O, exists as a zwitterion with a deprotonated carboxyl group and a protonated amine group. The crystal packing is stabilized by intermolecular N—H...O and O—H...O hydrogen bonds, building sheets parallel to the (001) plane.
