Intermetallic compounds represent an extensive pool of candidates for energy related applications stemming from magnetic, electric, optic, caloric, and catalytic properties. The discovery of novel intermetallic compounds can enhance understanding of the chemical principles that govern structural stability and chemical bonding as well as finding new applications. Valence electron-poor polar intermetallics with valence electron concentrations (VECs) between 2.0 and 3.0 e^–/atom show a plethora of unprecedented and fascinating structural motifs and bonding features. Therefore, establishing simple structure-bonding-property relationships is especially challenging for this compound class because commonly accepted valence electron counting rules are inappropriate.

电子贫乏的极性金属间化合物：复杂的结构，新型的簇和具有明显的电子离域的有趣的键合

金属间化合物代表了与能源相关的应用的广泛候选对象，这些应用源于磁，电，光，热和催化特性。新型金属间化合物的发现可以增强对控制结构稳定性和化学键合的化学原理的了解，并找到新的应用。价缺电子极性金属间化合物具有2.0和3.0之间价电子浓度（血管内皮细胞）ë ^- /原子显示前所未有和引人入胜的结构基序和粘合功能的过多。因此，对于这种化合物类别而言，建立简单的结构键与性质之间的关系尤其具有挑战性，因为普遍接受的价电子计数规则是不合适的。
