Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p> A congruent melting compound MgSrB₂O₅ was synthesized by high temperature solution method from the MgO‐SrO‐B₂O₃ system, and the structure was determined by single‐crystal X‐ray diffraction methods. The compound crystallizes in the monoclinic system, with space group <italic>P</italic>2₁/<italic>c</italic>. The crystal structure is composed of isolated B₂O₅ units and MgO₆ octahedra that are connected to form two‐dimensional [Mg₂B₄O₁₀] layers stacking along the <italic>c</italic> axis. The layers are bridged by the Sr²⁺ cations to form a three‐dimensional framework. The IR spectrum and the thermal properties of MgSrB₂O₅ were also reported. Additionally, detailed structure comparisons between MgSrB₂O₅ and other borates, such as Mg₂B₂O₅, Sr₂B₂O₅ and SrCdB₂O₅ are carried out and the first‐principle theoretical studies are performed to aid the understanding of electronic structures and linear optical properties.</p> </abstract>
