NaK15[B4O5(OH)4]6(NO2)2(CO3)·7H2O: assembly of an unprecedented mixed anion inorganic compound via a facile hydrothermal route

Abstract

The combination of multiple anions into one compound leads to new structure types with intriguing properties. Here, a new mixed anion compound NaK₁₅[B₄O₅(OH)₄]₆(NO₂)₂(CO₃)·7H₂O has been synthesized by a hydrothermal method. Notably, this compound simultaneously possesses [B₄O₅(OH)₄]²⁻, [NO₂]⁻, and [CO₃]²⁻ fundamental building blocks.
