首次合成了具有kbbf型结构的新型无铍锌酸盐BaZn3(BO3)2F2。BaZn3(BO3)2F2中相互作用的静电力在相邻的[ZnBO3F]∞单层中提供了更好的链接。BaZn3(BO3)2F2是第一个同时具有[ZnO3F]四面体和[ZnO6]八面体的硼酸盐，丰富了硼酸盐体系的结构化学。所有共面[BO3]三角形沿同一方向排列且密度高，这使得BaZn3(BO3)2F2在1064 nm处具有0.076 cal的大双折射率。这项工作对设计具有kbbf型结构的无铍硼酸盐具有重要意义。
A new beryllium-free zincoborate, BaZn3(BO3)2F2, with a KBBF-type structure has been synthesized for the first time. The electrostatic force of interaction in BaZn3(BO3)2F2 provides better linkage in neighboring [ZnBO3F]∞ single layers. BaZn3(BO3)2F2 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)2F2 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.
