Design, synthesis and structural study of a bisthiosemicarbazone ligand precursor of metallosupramolecular architectures

The increase on the investigation of different self-assembled architectures derived from thiosemicarbazone ligands are interesting due to the different metallosupramolecular architectures with several applications that can be obtained. The potentially tetradentate organic bisthiosemicarbazone ligand H₂L possesses two flexibles bidentate [NS] domains separated by a short and rigid spacer, which could stabilize several metal ions and thus different metallosupramolecular architectures. H₂L has been prepared by a condensation reaction between two equivalents of N-ethylhydrazinecarbothioamide and one equivalent of 1,1',1''-(benzene-1,3,5-triyl)tris(ethan-1-one), and was fully studies by using several techniques, including X-ray diffraction.
