The rich structural types of borates provide us with important sources of functional materials with excellent magnetic and optical properties. Three kinds of organic template borates were synthesized by solvothermal method. The crystal structures of these three borates were measured by X-ray single crystal diffraction, and the thermogravimetric properties of the related compounds were studied. Infrared isotherms.
