Two new sodium aluminum borates, Na AlB O and Na Al B O , have been successfully synthesized by the high-temperature solution method. They crystallize in the different space groups, P2 /c and P2/c, respectively. The B-O configurations of β-Na B O , Na AlB O and Na Al B O are compared to feature complicated different dimensional open-framework structures caused by the substitution of [BO ] by [AlO ] covalent tetrahedra. Moreover, the experimental results indicate that Na AlB O and Na Al B O have short ultraviolet (UV) cutoff edges (<187 nm). The first-principles calculations show that Na AlB O and Na Al B O have moderate birefringence (0.075 and 0.041@1064 nm, respectively).
