(S)-2-(1-Hydroxy­ethyl)benzimid­azolium dihydrogen phosphate

The asymmetric unit of the title compound, C(9)H(11)N(2)O(+)·H(2)PO(4) (−), is built up from a 2-(1-hydroxy­ethyl)benz­imid­a­zol­ium cation and a dihydrogen phosphate anion which are connected by an N—H⋯O hydrogen bond. The cation is roughly planar, the dihedral angle between the rings being only 1...

Descripción
Sumario:The asymmetric unit of the title compound, C(9)H(11)N(2)O(+)·H(2)PO(4) (−), is built up from a 2-(1-hydroxy­ethyl)benz­imid­a­zol­ium cation and a dihydrogen phosphate anion which are connected by an N—H⋯O hydrogen bond. The cation is roughly planar, the dihedral angle between the rings being only 1.4 (2)°. The S configuration is deduced from the synthetic pathway and supported by the refinement of the Flack parameter. Inter­molecular O—H⋯O and N—H⋯O hydrogen bonds build up a three-dimensionnal network.
