The deep eutectic solvents was first employed to solve the hydrolysis of Sb~(3+) cations in Sb(III)-oxyacid system to explore new nonlinear optical materials, producing a novel antimony(III) fluoride oxalate named NH_4Sb_2(C_2O_4)F_5. The title compound featured a 3D noncentrosymmetric structure composed of [Sb_2(C_2O_4) F_5]~- anionic clusters and NH~4~+ cations. The cooperative effect of the planar n-conjugated [C_2O_4]~(2-) anionic groups and the Sb~(3+) cations with stereochemicaly active lone pairs induce a relatively strong SHG response (l.l×KH_2PO_4) and a large birefringence (0.111@546nm), which was confirmed by detailed theoretical calculations. The overall performances indicate that NH_4Sb_2(C_2O_4)F_5 is a potential ultraviolet nonlinear optical material. The successful application of deep eutectic solvents in the synthesis for easy hydrolytic materials system opens the door to exploring new inorganic solid functional materials.
