This is what my syllabus states (and its confusing me what has simple molecular or giant molecular structure):

(ii) simple molecular, as in iodine and the fullerene allotropes of carbon
(C60 and nanotubes only)

(iii) giant molecular, as in silicon(IV) oxide and the graphite, diamond and
graphene allotropes of carbon

I just read about them on chemguide website (http://www.chemguideforcie.co.uk/201...g4p3a.html#top)

I'm typically confused in Nanotubes and Graphene (since they're explained in "simple molecular" portion and "giant molecular" as well.

yes, generally not well explained in text books.

graphite is giant molecular in 2 dimensions, with many layers in the 3rd dimension

graphene is giant molecular in 2 dimensions (one layer of graphite)

fullerenes have the same bonding as graphite (except for the inclusion of 5 membered rings when curved surfaces are needed), but are simple molecular.

nanotubes are tubes of graphene with caps of curved graphene (5 membered rings), which occupy a grey area as the tube length could vary from small (simple molecular) to very long indeed (giant molecular)
