This study is directed towards assessing hydrogen bond acceptor/donor capabilities of heavier group 14 homologues of HCN and HNC. A structural, energetic and topological study using (MP2, CCSD(T)), electrostatic potential (EP) and quantum theory of atoms in molecules (QTAIM) methodologies was carried out on HNX⋯HNX and HXN⋯HXN dimers and their respective monomers, where X = C, Si, Ge, Sn and Pb. The obtained results suggest the presence of weak hydrogen bonds in both kinds of complexes, and remarkably Ge and Sn act as unconventional hydrogen donors.
本研究旨在评估HCN和HNC较重的第14族同系物的氢键受体/供体能力。使用(MP2、CCSD(T))、静电势(EP)和分子中的原子量子理论(QTAIM)方法,对HNX⋯HNX和HXN⋯HXN二聚体及其各自的单体进行了结构、能量和拓扑研究,其中X = C、Si、Ge、Sn和Pb。所得结果表明,在这两种配合物中均存在弱氢键,并且值得注意的是,Ge和Sn作为非常规氢供体。
