Fecha de publicación: | 2020 | Editor: | Elsevier | Citación: | Journal of Molecular Structure 1201: 127217 (2020) | Resumen: | Theoretical electron density (QTAIM) studies in the gas-phase have shown that the attachment of the BH3 group to the metal atom in complexes [Mn(κ3N,H,H-iPr2bzamBH3)(CO)3] (1) and [Ru(η5-C5Me5)(κ3N,H,H-iPr2bzamBH3)] (2) (HiPr2bzamBH3 = N-trihydridoborane-N,N′-bis(isopropyl) benzamidine) is symmetric in the latter but asymmetric in the former, and involves two B–H–metal interactions that are intermediate between κ1H (Shimoi type) and κ2H,B (agostic type). The herein reported results, coupled to previous ones on related complexes having a similar tripod κ3N,H,H-borane ligand, show that the bonding similarities and differences within each particular M(μ-H)2B moiety are not related to the type of metal atom, nor even to its coordination geometry, but mainly to the molecular symmetry. | Versión del editor: | https://doi.org/10.1016/j.molstruc.2019.127217 | URI: | http://hdl.handle.net/10261/201884 | DOI: | 10.1016/j.molstruc.2019.127217 | ISSN: | 0022-2860 |
