N-Methylpiperidine betaine (MPB) and L(+)-tartaric acid form a six-molecular non-centrosymmetric crystalline complex through two OAHÁ Á ÁO@C and four COOÁ Á ÁHOOC hydrogen bonds. The structure of this co-crystal has been determined by X-ray diffraction. The molecular structure of the title compound
1,3-Bis(carboxymethyl)imidazolium bromide [(C 7 H 9 N 2 O 4 ) + Br À ] has been studied by X-ray diffraction, FT-IR and Raman spectroscopy. In the crystalline state, two 1,3-bis(carboxymethyl)imidazolium bromide molecules are hydrogen-bonded via carboxylic groups forming a symmetric dimer. Within th
