Study on the coordination of the hydroxyl group: Crystal structure and FT-IR spectra of potassium hydrogen galactarate

Potassium hydrogen galactarate monohydrate was prepared for the first time. X-ray diffraction analysis showed that the K+ ion in this complex is hepta-coordinated, and two of the four hydroxyl groups are coordinated to the K+ ion. The complex forms a hydrogen bonding network. The results of the FT-IR spectra measurement an in agreement with the conclusion of X-ray crystal structural study.
