A new rubidium fluorooxoborate, RbB3O4F2, was structurally designed and synthesized by using the strategy of fluorine-introduction into borates. Interestingly, RbB3O4F2 presents the novel [B3O4F2]- chains formed by the unprecedented [B3O5F2]3- fundamental building block. More importantly, RbB3O4F2 has a large birefringence and a deep-UV cutoff edge. The finding of novel [B3O5F2]3- FBB and [B3O4F2]- chains in RbB3O4F2 greatly enriches the structural diversity of fluorooxoborates.
