A proximity enforcing diarylsilane ligand is reported,
which gives
rise to unusual Si–H···M interactions with the
d10 metal ions Cu+ and Ag+ upon complexation.
These interactions are studied in detail both experimentally and computationally
and can be classified to be weakly agostic in nature for the Si–H···Cu
interaction. The Si–H···Ag interaction has more
signatures of an electrostatic contact.
The reaction of (5-Ph 2 P-Ace-6-) 2 MeSiH with [(C 2 H 4 ) 2 RhCl] 2 proceeded via elimination of ethylene and oxidative addition of the Si−H bond at rhodium and provided the rhodium(III) complex (5-Ph 2 P-Ace-6-) 2 MeSiRh(H)Cl (1) possessing a reverse agostic interaction of the type Rh−H•••Si, which was characterized by Hirshfeld atom refinement (HAR) of single-crystal X-ray diffraction data. This technique allows the precise and accurate determination of hydrogen positions also for heavier transition-metal hydrides. The bonding situation in the Rh−H•••Si interaction was further analyzed using a set of complementary bonding indicators, such as the compliance matrix analysis or real-space bonding indicators derived from the electron and electron pair densities. The reaction of (5-Ph 2 P-Ace-6-) 2 MeSiH with [(CO) 2 RhCl] 2 occurred via elimination of hydrogen chloride and produced the rhodium(I) complex (5-Ph 2 P-Ace-6-) 2 MeSiRh(CO) 2 (2).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
