Synthesis and structure of new Schiff base derivatives obtained from 2-(formylphenyl)mercury bromide

Reactions of (2-formylphenyl)mercury(II) bromide 10 with primary amines give mono-, bis- and tris- Schiff base derivatives (11–18). Structures of the synthesized compounds show the presence of five-membered intramolecular Hg⋯N interaction. Luminescence studies of the compounds have been performed. Attempts to use the synthesized compounds for binding neutral donor molecules or fluoride ions were unsuccessful.
