View source for Sandwich compound


Sandwhich compound are a nice example in organochemistry <br>
where metal atoms covalently bond to carbon atoms in a densely packed compact (somewhat gemstone like) way. <br>

Transition metal elements usually have a high [[bond order]] due to their orbitals being filled up <br>
all the way to the d orbitals that are huge and rich in hybridization options.<br>

== Eventual applicability to attach graphene sheets onto gemstone like compounds as (passivating) surface cover ?? ==

'''Question:''' Could this type of bond also work to bond a graphene sheet onto a gemstone like struture below?

'''If such a graphene cover is possible then this could be used for:'''

(1) Bigger gear teeth on bigger molecular machine elements, like approximating evolute or cycloid profiles

(2) The passivation of materials that are not (or may not) be passivatable by hydrogen or other means (methylation, ...). 
* [[Transition metal monoxides]] (there are many of these with simple crystal structure) 
* Pure metals (as far as they can be used due to surface diffusion limitations)

----
It's not called a "burger compound". <br>
<small>Just added that note here to find it with that term too.</small>
