Borates with tunable structure and property currently provide a new rich source for solid-state chemistry and materials science. Realization of property improvement via simple structural regulation is a rising hot spot of borate-based research. Herein, a new aluminoborate fluoride, LiCsAlBOF, with [BO] clusters was discovered, and it was found to melt congruently. The optimally aligned [BO] dimers within [BO] clusters make LiCsAlBOF an enhanced birefringence, which is about 4.3× higher than its congener compound LiCsBO with same [BO] clusters. Structural analysis and additional theoretical calculations have revealed the origin of enhanced optical anisotropy.
