The C-C bond length in graphite (141.5 pm) is shorter than a typical C-C single bond (154 pm) due to the delocalization of $\pi$ electrons. Each carbon atom in graphite is sp² hybridized, forming three sigma bonds and one unhybridized p orbital. These p orbitals overlap to form a delocalized $\pi$ electron system across the layers, imparting partial double bond character to the C-C bonds, thus shortening them.
