Question

Why a silicon analogue of graphite does not exist?

Answer 1

Graphite is a full scale atom which is comprised of hexagonal carbon rings. The carbons have $sp^2$ hybridization and frame 2 sigma and one pi bond each.

Silicon, being in a similar gathering has likenesses yet it doesn't shape full scale atoms just with itself like carbon. This is because of the catenation property of the components.

Catenation is the property of a component to shape covalent bonds with itself. Carbon has the most astounding catenation tendency because of which it frames expansive chains. An explanation behind silicon having lesser catenation property than carbon is expected according to the individual bond energies.

A C-C bond is solid, giving high steadiness to the atom whereas a Si-Si bonds isn't so solid. This is the reason silicon can't frame large scale atoms with itself like carbon.
