The proton magnetic resonance spectrum of single crystals of HgSO∙1H2O has been investigated. This crystal is of interest since, according to the X-ray structure analysis, it appears likely that one of the protons of the water molecule is hydrogen-bonded in the structure, while the other is free. Two non-equivalent sets of parallel H–H vectors have been observed in agreement with the crystal symmetry. The angles of one of the intramolecular H–H vectors with the crystallographic axes are α = 58°, β = 95°, and γ = 36°. The results are consistent with the suggestion that one of the protons does not form a hydrogen bond in the crystal.
