开发了一种低温离子热法，可以轻松合成单晶形式的卤化物碳酸盐 Ba3Cl4CO3。这使得首次确定该材料的晶体结构成为可能。单晶X射线衍射数据分析表明，氯化碳酸钡在斜方空间群Pnma（Z=4）中结晶，a=8.4074（11），b=9.5886（12），c=12.4833（15）Å（Rw=0.0392）。它表现出一种复杂的结构，其中三维网络是由共享面的阴离子中心八面体链的交联形成的。
A low-temperature ionothermal method for the facile synthesis of the halide carbonate, Ba3Cl4CO3, in single-crystalline form has been developed. This has enabled the first determination of the crystal structure of this material to be carried out. Analysis of single-crystal X-ray diffraction data indicates that barium chloride carbonate crystallises in the orthorhombic space group Pnma (Z=4), with a=8.4074(11), b=9.5886(12), c=12.4833(15)Å (Rw=0.0392). It exhibits a complex structure in which a three-dimensional network is formed from cross-linking of chains of anion-centred octahedra that share faces.
