In the title salt, [Hg(NCS)(CH4N2S)3]Cl, the Hg2+ ion is coordinated in a severely distorted tetrahedral manner by three thiourea groups and one thiocyanate anion through their S atoms. The S—Hg—S angles vary widely from 87.39 (5) to 128.02 (4)°. Weak intramolecular N—H
S hydrogen bonds are observed, which form S(6) ring motifs. In the crystal, the ions are linked by N—HN and weak N—HCl interactions, generating a three-dimensional network.

In the title molecular salt, C6H11N3O22+·2C6H2N3O7−·2H2O, the histidine molecule exists as a histidinium dication, being protonated at the N atom of the imidazole ring. The charges are balanced by two picrate anions and the compound crystallizes as a dihydrate. In the crystal, the components are linked via N—HO and O—HO hydrogen bonds and weak C—HO interactions, forming a three-dimensional supermolecular structure.
