Space group of graphite
WebAbstract. Lithium ion transport was accelerated within graphite by controlling its d -spacing as well as its functional groups. By oxidizing bare graphite under a mild condition, expanded graphites (EG* where * = functional groups) were obtained with increasing d -spacing from 0.3359 nm to 0.3395 nm as well as with functional groups formed on ... Web1. jan 1997 · This is a revised version of the original graphite structure phase. We have preserved the old graphite structure page here. According to Wyckoff, hexagonal graphite may be either flat, space group P6 3 /mmc (#194) or buckled, spage group P6 3 mc (#186). If it is buckled, the buckling parameter is small, less than 1/20 of the ``c'' parameter of ...

WebGraphite is composed of layers of carbon atoms that are arranged in 6-membered, hexagonal rings. These rings are attached to one another on their edges. Layers of fused rings can be modeled as an infinite series of fused benzene rings (without the hydrogen atoms). Carbon atoms in these ring arrays are in the sp2-hybridized state.
