Synthesis, structure, and thermal and photoluminescent properties of a zinc(II) sulfate 4′-phenyl-terpyridine compound

ABSTRACT

Reaction between 4′-phenyl-terpyridine (L) and a Zn (II) salt (zinc sulfate heptahydrate) led to the formation of the complex {[Zn(μ₂-O₂SO₂)L]·3H₂O}_n (1), which was obtained by hydrothermal synthesis. Its structure was characterized by elemental analysis, and IR and single-crystal X-ray diffraction. In 1, the Zn atom is envisaged as possessing distorted N₃O₂ irregular trigonal bipyramidal coordination geometries. The compound shows interesting photoluminescent properties in solid state, which are reported along with their TG-DTA thermal decomposition processes.
