Synthesis, crystal growth and structural characterization of lithium fumarate semi-organic single crystals

• Lithium fumarate was synthesized and structure was reported.
• LF can be exploited for applications below 270 °C.
• Wide optical transparency window between 290 nm and 1100 nm.

Lithium fumarate was synthesized and single crystals have been grown by the slow evaporation method. The crystal structure of lithium fumarate has been determined by single crystal X-ray diffraction and it belongs to the monoclinic system. The thermal stability and melting point of the material of LF crystal have been investigated by means of thermogravimetric analysis and differential thermal analysis. The UV–vis–NIR transmittance spectrum was recorded in the range 200–1100 nm, to find the suitability of the single crystal for various optical applications. The mechanical stability of the crystal was analyzed by Vickers microhardness studies.
