In recently published book (Shabalin IL, Ultra-High Temperature Materials - I, Springer, Dordrecht, 2014) I have suggested to apply for it so-termed "specific bond enthalpy", i.e. average bond enthalpy per C-C bond order (please see the file attached). However, it seems to me that for the intermediate carbon families (e.g. the fullerene family) it should be applied some parameters else; maybe geometrical ones, for example, the pyramidalization angle or something similar, although more likely there is some kind of correlation between the angle and bond enthalpy. Could anyone share with me their personal views on the problem? I would be also glad to get from everybody any remarks on my list of carbon allotropes (polymorphs, polytypes) as more likely some of them have not been listed yet. I believe the answers to these questions will help us to create more perfect classification of all the carbon forms experimentally observed and theoretically predicted.
You might be interested by this recent paper, partly answering your question.

Dear Alain, Many thanks to you! However, it is only terminology... Certainly, it is very important, but I am thinking about total carbon classification.
Dear Igor;
Do you intend to classify all carbon allotropes?
This includes, for example, those mentioned in:

Dear Juan, Thank you for your response. You can find the classification proposed in the file attached to the question (this is from Shabalin IL, Ultra-High Temperature Materials - I, Springer, Dordrecht, 2014).
