The conflict between beneficial layered structure for performances and layered growth habits in KBe 2 BO 3 F 2 (KBBF) always restricts its practical applications. A beryllium‐free KBBF family member, Zn 2 BO 3 (OH), is explored to feature the same topological layer with KBBF by replacing [BeO 3 F] 5− with [ZnO 3 (OH)] 5− and excellent UV performances. It exhibits a second harmonic generation response of about 1.5 × KH 2 PO 4 with the UV cutoff edge of 204 nm. The birefringence of Zn 2 BO 3 (OH) in the visible region is about 0.067, which is larger than those of commercial UV crystals LiB 3 O 5 , CsB 3 O 5 , and CsLiB 6 O 10 . Additionally, it has excellent thermal and water‐resistant stabilities. Owing to the removal of interlayer cations, Zn 2 BO 3 (OH) shows better growth habits than KBBF while achieving the balance between beneficial layered structure and layer tendency.
