The structure of the title compound, (C14H16N)2[HgCl2(SO4)], consists of an infinite chain propagating along the c direction, containing HgII ions tetracoordinated by two bridging O atoms of bis-monodentate sulfate anions and two chloride ligands. In the the crystal, N—HO hydrogen bonding between the cations and the anionic chains consolidates the packing. The crystal structure was determined from an inversion twin with approximately equal twin domains.

In the title salt, [(CH3)2CH]2NH2]+·[C6H5PO2(OH)]−, the anions are linked by pairs of O—HO hydrogen bonds, forming inversion dimers. These dimers are bridged by the cations via N—HO hydrogen bonds, leading to a three-dimensional structure.
