1,3-Bis(hydroxymethyl)benzimidazolin-2-one

Abstract

The title compound, C9H10N2O3, crystallizes with one and a half molecules in the asymmetric unit, one lying on a general position and the other on a twofold rotation axis. The dihedral angle between the two independent benzimidazole ring systems is 18.96 (5)°. In the crystal, molecules are linked into a three-dimensional network by O—H...O hydrogen bonding involving N-hydroxymethyl and carbonyl groups, and C—H...O hydrogen bonds.
