摘要

Two new polyborates [(CH₃NH₃)₄][B₁₄O₂₀(OH)₆] (1) and [Zn(en)₂{B₇O₁₀(OH)₃}] (2, en = ethylenediamine), which are constructed by different types of B₇ clusters, had been synthesized under solvothermal conditions by utilizing different directing agents. Compound 1, which was directed by methylamine, has an isolated [B₁₄O₂₀(OH)₆]⁴⁻ anionic cluster constructed by [B₇O₁₀(OH)₃]²⁻ (B₇-I) cluster, and then the [B₁₄O₂₀(OH)₆]⁴⁻ clusters are further linked to a 3D supramolecular framework through hydrogen bonds. Compound 2 is a coordination polymer and has a 2D layer structure constructed by [B₇O₁₀(OH)₃]²⁻ (B₇-II) clusters through a four-connected mode. The 2D oxo-boron layered structures are further linked to 3D B–O–Zn network by Zn–O bonds. The band gaps of compounds 1 and 2 indicated that they could have potential applications as semiconductor and deep-UV materials, respectively.
