Abstract

The structure of the title compound, [HN(C2H4OH)(3)](+).-H2PO4- or C6H16NO3+.H2PO4-, contains two distinct dihydrogenphosphate anions and two triethanolammonium cations in the asymmetric unit. The H2PO4 units are linked in a polymeric chain by strong P-OH...O-P hydrogen bonds along the [010] direction, while the (H2PO4)(-) and [HN(C2H4OH)(3)](+) ions are connected by O-H...O hydrogen bonds to yield sheet-like entities. The triethanolammonium cation shows a tripodal conformation and the ammonium H atom forms an intramolecular trifurcated hydrogen bond with the O atoms of the three ethanol groups.
