MgNi2Bi4 was grown from the reaction of magnesium and nickel in excess bismuth flux. It forms as large, malleable crystals with a new structure type in orthorhombic space group Cmcm. The structure contains a building block common to Ni-Bi binary phases-nickel zigzag chains running along one direction and surrounded by bismuth. Magnetic susceptibility and transport measurements indicate that the compound is metallic; this is supported by calculations of density of states. Crystal orbital Hamilton population analyses indicate that Ni-Bi interactions are the strongest bonding interactions in the structure, whereas Bi-Bi bonding between the layers is negligible, making MgNi2Bi4 a potential two-dimensional material.

MgNi2Bi4的助熔剂合成及其与NiBi3的结构关系。

MgNi2Bi4是由镁和镍在过量的铋通量下的反应生成的。它在正交空间群Ccm中形成具有新结构类型的大的可延展晶体。该结构包含一个Ni-Bi二元相-镍之字形链共有的构件，该链沿一个方向延伸并被铋包围。磁化率和迁移率测量表明该化合物是金属的。这由状态密度的计算来支持。晶体轨道汉密尔顿人口分析表明，Ni-Bi相互作用是结构中最强的键相互作用，而层之间的Bi-Bi键则可忽略不计，从而使MgNi2Bi4成为潜在的二维材料。
