Diamond is sp3-hybridized carbon. Graphite is sp2-hybridized carbon as planes of edge-fused aromatic rings stacked into a lamellar solid. http://cst-www.nrl.navy.mil/lattice/struk/a4.html diamond "crystal strucure" http://cst-www.nrl.navy.mil/lattice/struk/a9.html graphite "crystal strucure" For more information, see "Advanced Inorganic Chemistry," 6th Ed., Cotton, Wilkinson, et al., 1999, pp. 210-212. "Organic Chemistry," 5th Ed., Morrison and Boyd, 1987, pp. 438; 1168-9. Note that there are several allotropes and polymorphs of elemental carbon: graphite, diamond(cubic)/lonesdaleite(hexagonal), fullerenes, cyclopolycarbyne, and SC4 (Phys. Rev. B, 53, 5051 (1996). The world is rich with knowledge. Bestir your backside and go after some. Uncle Al!
