A new beryllium-free zincoborate, BaZn3(BO3)(2)F-2, with a KBBF-type structure has been synthesized for the first time, showing better linkage in neighboring single layers and large birefringence. This work enriches the structural chemistry of borate system and holds significance in designing beryllium-free borates with a KBBF-type structure.
A new beryllium-free zincoborate, BaZn3(BO3)(2)F-2, with a KBBF-type structure has been synthesized for the first time. The electrostatic force of interaction in BaZn3(BO3)(2)F-2 provides better linkage in neighboring [ZnBO3F](infinity) single layers. BaZn3(BO3)(2)F-2 is the first case of borates with both [ZnO3F] tetrahedra and [ZnO6] octahedra, enriching the structural chemistry of borate system. All the coplanar [BO3] triangles align in the same direction with a high density, which endows BaZn3(BO3)(2)F-2 with a large birefringence of cal. 0.076 at 1064 nm. This work is of great significance to design beryllium-free borates with a KBBF-type structure.
