On the verification of binding modes of p-dimethylaminobenzaldehyde thiosemicarbazone with mercury(II). The solid state studies

- Two compounds of thiosemicarbazone, fluorescent chemosensor, with Hg ion were characterised.
- Inorganic anion influences the binding mode of thiosemicarbazone ligand to Hg ion in solid state.
- The crystal packing is controlled by Hg chelate ring-phenylene ring π···π stacking interactions.
