Metal Tetramesityl Compounds, M = V, Mo, Ru, Os, Rh, Ir Peer Review

Lead/Introduction:


 * I believe that tetramesityl should be one word, so make sure that you keep that consistent amongst the title and the rest of the article.
 * In the first sentence, you say transition metal (IV) compounds, which I think is referring to the oxidation state of the metals, but I think that you can take the (IV) nomenclature out in the first sentence or explain it more completely so that the reader knows that you are referring to oxidation state and not group 4 metals.
 * It might be best to say "underexplored" instead of "unexplored", as "unexplored" implies that the compounds have not been studied in detail at all, but the fact that there is a wikipedia page and numerous academic articles about them indicates that they have been explored to some degree.
 * Maybe you could offer a few examples as to what some of the unique electrochemical, magnetic, and optical properties are so that your reader is prepared for what you will describe in more detail later in the article.
 * I'm not sure what you mean when you say that their attributes "surpass" those of their isostructural counterparts in group 14 - are you talking about carbon/silicon/germanium tetramesityl compounds? Are those used in MOFs, polymers, devices, etc.? Some clarity here would be helpful, as well as maybe some images of what compounds you are talking about and what applications they are used in.

Metal Tetramesityl Compounds:


 * Some lead references for the synthesis and identification of some of your compounds would be helpful for the readers that want to go more in depth and are using your article as a jumping off point. They probably don't each need to be discussed in detail, but offering the reference would be helpful.
 * Another reference to where you are talking about the Cr(arly)4 research would be helpful/necessary when you are discussing research.
 * I'm not sure what you mean when you say "access these complexes optically" - you should describe this techniqeu to your reader in greater detail. I'm also not sure what a diluent matrix is, so it would be very difficult for a non-expert to understand what you are talking about here. I would provide more detail about these techniques or talk about them in a broader, more reader-friendly way.
 * I think Os(iv) and Ru(iv) should be capitalized if you are discussing oxidation state: Os(IV) and Ru(IV).
 * When you are discussing dn counts, you should make the number a superscript. I'm also not sure what you mean when you say that the compounds exhibit "robustness" - what is this in reference to?
 * I'm not sure what you mean by air chromatography - flash column chromatography or gas chromatography or something else?

Synthesis of Metal Tetramesityl Compounds:


 * I'm not positive about this, but I've seen in the literature that when you are referring to Mesityl as "Mes" it should be capitalized and not "mes".
 * For the Tetramesityl Iridium synthesis - do the authors of this paper provide a reason for why the synthesis of the tetramesityl compound works with IrCl3 and not IrCl3(THF)3? This could be helpful in elucidating more of the story as to how and why these compounds form.
 * For the tetramesityl iridium synthesis do the authors provide any indication of what the oxidation decomposition product is when the compound is heated under air? It could be an interesting comparison for possible reactivity of the compound.
 * For the tetramesityl iridum crystal structure, when you discuss the bond lengths of the Ir-C bonds, it would be helpful to include information about what is "normal" for Ir-C bonds - i.e. what are the normal single/double bond lengths and what category would this Ir-C compound fall into?
 * I think there is a typo where you say low-spin dS iridium(IV) - I think you mean to say low-spin d5.
 * When you discuss the tetraarylruthenium(IV) complex synthesis, it would be helpful if instead of using the chemical formula of the reactants you did drawings of them instead - it would make it easier for your reader to understand what reaction is taking place and how the coordination to the metal happens.
 * You have a typo where you say "In order to improve the yield of tetraarylruthenium(IV)...".

Wikipedia Peer Review Questions:

Lead:


 * Does the Lead include a brief description of the article's major sections? - It might be helpful to include a sentence about what you will discuss in the article - overview, synthesis, applications, etc.
 * Does the Lead include information that is not present in the article? - You discussed a lot of applications of other types of tetramesityl compounds, but didn't discuss any applications of the related tetramesityl transition metal compounds. I'm not sure if there are currently any applications of these transition metal complexes, but if there are any examples, it could be interesting to include a section in the later part of your article where you discuss that and how it compares to the group 14 applications.

Content:


 * Is the content added up-to-date? - In your introduction you mentioned that the exploration of these compounds is relatively unexplored, but if you could include any recent applications in reactivity/catalysis/applications of these molecules, it would make the article feel more interesting and complete to the uninitiated reader, as well as round out some of your discussion of the synthesis if you can include something about the applications.

Sources and References:


 * I see that you put references in at the end of most of the paragraphs, but it might be helpful to your reader, particularly in the earlier paragraphs, to place citations at the end of some of the sentences as well. This would be helpful because then your reader could know exactly what information is from which reference which they could use to do further research on their own if they wish.

Images and Media:


 * I really like the images that you have of the optimized structures of the tetramesityl transition metal compounds, but it would be helpful if you could include some ChemDraws or reaction schemes when you are discussing synthesis and reactivity. Seeing the compound drawn out in one way or another would allow your reader to visualize the molecules, as it is sometimes difficult to picture them from a crystal structure alone.
