Synthesis, crystal structure, optical properties and bactericidal activity of a new organic-inorganic hybrid: Benzyl triethylaminium tetrachloromanganate(II)

In this work, a lead-free organic-inorganic hybrid crystal with dual functions of green-emission and bactericidal activity, benzyl triethylaminium tetrachloromanganate(II) ([BzTEA]2[MnCl4]), was synthesized by the slow evaporation solution growth technology and characterized by single-crystal and power X-ray diffraction, IR spectrum, Scanning Electron microscopy, and PL spectrum. The compound crystallized in the monoclinic space group P2(1)/c. The thermal study revealed that the material showed good thermal stability and can be used for applications below 222.1 degrees C. The material had excellent optical properties as it fluoresced green under 350 nm UV light. The compound exhibited favorable bactericidal activity against Staphylococcus aureus and Escherichia coli.
