Multicenter bonding, one of the common phenomenon in p-block as well as d-block metals, is a rare phenomenon in s-block metals. Very few examples, if not none, are there in the literature. Herein, we have proposed a 3c-2e bonding scenario involving alkaline earth metals. Different bonding analyses confirm the presence of multicenter 3c-2e bonds in these proposed compounds. All these analyses are strikingly similar as found in diborane. These proposed molecules are found to be thermodynamically stable.

s块金属中的多中心键合：理论的见解

多中心键合，在常见的现象一个p -嵌段以及d区金属，是在一个罕见的现象S-区金属。文献中只有很少的例子，如果没有的话。在此，我们提出了一种涉及碱土金属的3c-2e结合方案。不同的键合分析证实了这些拟议化合物中存在多中心3c-2e键。所有这些分析与乙硼烷中的发现非常相似。发现这些提出的分子是热力学稳定的。
