Título: | Theoretical study of dihydrogen bonds between (XH)2, X = Li, Na, BeH, and MgH, and weak hydrogen bond donors (HCN, HNC, and HCCH) |
Autor: | Alkorta, Ibon CSIC ORCID ; Zborowski, K. K.; Elguero, José CSIC ORCID; Solimannejad, Mohammad | Fecha de publicación: | 2006 | Editor: | American Chemical Society | Citación: | The journal of physical chemistry, A, Molecules, spectroscopy, kinetics, environment & general theory 110: 10279- 10286 (2006) | Resumen: | The dihydrogen-bonded (DHB) complexes formed by (XH)2, with X = Li, Na, BeH, and MgH, with one, two, and four protonic molecules (HCN, HNC, and HCCH) have been studied. These complexes have been compared to those of the XH monomers with the same hydrogen bond donor molecules. The energetic results have been rationalized based on the electrostatic potential of the isolated hydridic systems. The electron density properties have been analyzed within the AIM methodology, both at the bond critical points and the integrated values at the atomic basins. Exponential relationships between several properties calculated at the bond critical points (ρ,Δ2ρ, λi, G, and V) and variation of integrated properties (energy, charge, and volume) vs the DHB distance have been obtained. © 2006 American Chemical Society. | Versión del editor: | http://dx.doi.org/10.1021/jp061481x | URI: | http://hdl.handle.net/10261/73617 | DOI: | 10.1021/jp061481x | Identificadores: | doi: 10.1021/jp061481x issn: 1089-5639 |
