A series of alkaline earth metal fluorooxoborates , MB 4 O 6 F 2 (M = Ca, Sr, Ba) with functional [B 4 O 6 F 2 ] ∞ groups, have been synthesized. The diffuse‐reflectance spectra measurements indicate that the cutoff edges of title compounds are below 190 nm. Moreover, the first‐principle calculation results demonstrate that MB 4 O 6 F 2 (M = Ca, Sr, Ba) have large birefringence of 0.091, 0.089 and 0.085 at 1064 nm. Both experimental and theoretical studies suggest that MB 4 O 6 F 2 (M = Ca, Sr, Ba) are promising birefringent materials for deep‐UV applications. For more information, see the Communication by y.
