Abstract

The computation of metal-silyl interaction energies indicates the existence of situations where the silyl group behaves as a Z-type ligand according to Green's covalent bond classification method. It is shown that a scale of relative intrinsic silylicity Π, defined as the ratio of the intrinsic silyl-to-triflate interaction energy of a silyltriflate taken as reference compound and that of the silyl-to-metal interaction of given complex, can reveal in a straightforward manner the propensity of SiR₃ groups to behave chemically as metal-bound "silyliums" [SiR₃]+. Emblematic cases of the literature, either taken from the Cambridge Structural Database or constructed for the purpose of this study, were also investigated under the lights of ETS-NOCV and QTAIM analyses. It is shown in one case, i.e. POBMUP the iridium-POCOP complex isolated by Brookhart et al., how slight variations of molecular charge and structure can affect drastically the relative intrinsic silylicity of the SiEt₃ group that is weakly bonded to the hydrido-iridium motif.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 May 2018.
All research outputs
#14,366,209
of 24,525,936 outputs
Outputs from Chemistry - A European Journal
#10,714
of 22,865 outputs
Outputs of similar age
#168,119
of 336,686 outputs
Outputs of similar age from Chemistry - A European Journal
#157
of 698 outputs
Altmetric has tracked 24,525,936 research outputs across all sources so far. This one is in the 40th percentile – i.e., 40% of other outputs scored the same or lower than it.
So far Altmetric has tracked 22,865 research outputs from this source. They receive a mean Attention Score of 3.9. This one has gotten more attention than average, scoring higher than 52% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 336,686 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 698 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 75% of its contemporaries.
