Boron atoms and oxygen atoms can form units such as BO3 plane triangular tetrahedron, and BO3 and BO4 further form boron polyanions of different shapes and sizes. 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. Compound 1 belongs to monoclinic system and is an isolated borate complex. The molecular formula of compound 1 is Ni` [Nu CH2CH2NH2H3] 路[B5O7OHH3], the space group is P21c, and the unit cell parameter (ah8.9720h8)?
