A novel crystal[(CH_3O)_2CO]_3Li_2[C_2BF_2O_4]_2 was synthesized and fully characterized by FT-IR and single-crystal X-ray diffraction analysis.It crystallizes in monoclinic system,P2_1/n space group,with a=8.1749(2),b=10.7449(2),c=12.8665(3) A,β= 94.654(2)°,V= 1126.45(4)A~3,Z = 2,D_c= 1.644 g/cm,F(000) = 568,μ = 1.498 mm~(-1),M_r= 557.77 g/mol,the final R = 0.0334 and wR = 0.0903.The structure analysis revealed that each Li atom is three-coordinated and adopts1.5 O atoms of two different dimethyl carbonates and one O atom of C_2BF_2O_4~-.Thermal stability and infrared spectra analysis were studied and discussed.

It crystallizes in monoclinic system, P2_1 / n space group, with a = 8.1749 ( B = 10.7449 (2), c = 12.8665 (3) A, β = 94.654 (2) °, V = 1126.45 (4) A~3, Z = 2, D_c = 1.644 g / cm, F ) = 568, μ = 1.498 mm -1, M_r = 557.77 g / mol, the final R = 0.0334 and wR = 0.0903. The structure analysis revealed that each Li atom is three-coordinated and polarity 1.5 O atoms of two different dimethyl carbonates and one O atom of C_2BF_2O_4 ~ .Thermal stability and infrared spectra analysis were studied and discussed.
