摘要
Two borate-carbonates Ba4M(CO3)2(BO3)2(M =Ba, Sr) have been successfully synthesized in the open air representing the first examples of borate-carbnate complex.Their structures were determined by single crystal X-ray diffraction and they both crystallize in same space group, Pnma.Their structures feature a Ba/Sr-based three dimensional framework composed of the BaO8 polyhedra(the SrO8 polyhedra), isolated BO3 and CO3 triangles. Detailed structure analysis shows that the intergrowth of [Ba3(BO3)2]/[Ba2Sr(BO3)2] and [BaCO3] layers favors the formation of these two borate-carbonates. In addition, their syntheses, spectroscopic properties and thermal behaviors were investigated.
本文中,我们成功合成了两种复合的硼酸-碳酸盐Ba4M(CO3)2(BO3)2 (M=Ba,Sr).这是第一例在开放体系下合成的硼酸-碳酸盐.它们的结构由单晶X射线衍射确定,结晶在相同的Pnma空间群.它们的晶体结构是由BaO8多面体(SrO8多面体)、孤立的BO3和CO3三角形组成的三维网络结构.详细的结构分析表明,共生长的[Ba3(BO3)2]/[Ba2Sr(BO3)2]和[BaCO3]层是有利于这两种硼酸-碳酸盐的合成的.此外,还研究了它们的合成、光谱性质和热行为.
