Three polyborates, namely, LiNaBO, LiNaBO, and LiNaCaSrBOF, were synthesized via the high-temperature solution method. All of them feature high-symmetry [BO] units, yet their anion groups exhibit distinct dimensions. LiNaBO features a three-dimensional anionic structure of [BO] framework, which is composed of three units: [BO], [BO], and [BO]. LiNaBO possesses a one-dimensional anionic structure of [BO] chain consisting of [BO] and [BO] units. The anionic structure of LiNaCaSrBOF is composed of two zero-dimensional isolated units, namely, [BO] and [BO]. The novel FBBs [BO] and [BO] are present in LiNaBO and LiNaBO, respectively. The anionic groups in these compounds exhibit a high degree of polymerization, thereby augmenting the structural diversity of borates. And the crystal structure, synthesis, thermal stability, and optical properties were meticulously discussed to guide the synthesis and characterization of novel polyborates.
通过高温溶液法合成了三种多硼酸盐，即LiNaBO、LiNaBO和LiNaCaSrBOF。它们均具有高对称性的[BO]单元，但其阴离子基团呈现出不同的维度。LiNaBO具有由[BO]框架构成的三维阴离子结构，该结构由三个单元组成：[BO]、[BO]和[BO]。LiNaBO拥有由[BO]和[BO]单元组成的[BO]链的一维阴离子结构。LiNaCaSrBOF的阴离子结构由两个零维孤立单元组成，即[BO]和[BO]。新型的FBBs [BO]和[BO]分别存在于LiNaBO和LiNaBO中。这些化合物中的阴离子基团表现出高度的聚合度，从而增加了硼酸盐的结构多样性。并且对晶体结构、合成、热稳定性和光学性质进行了详细讨论，以指导新型多硼酸盐的合成与表征。
