Abstract
Local attractions characterize the interanionic O - H···O hydrogen bonds in crystalline potassium hydrogenoxalate. This is the conclusion of theoretical and experimental studies on the electron density distribution. This contradicts a recent claim that such interactions are electrostatically repulsive. The picture shows the Laplacian function of the electron density in the region of the hydrogen bond.
