WebIn the hexagonal family, the crystal is conventionally described by a right rhombic prism unit cell with two equal axes ( a by a ), an included angle of 120° ( γ) and a height ( c, which can be different from a) perpendicular to the two base axes. The hexagonal unit cell for the rhombohedral Bravais lattice is the R-centered cell, consisting ... WebWhen an element exists in more than one crystalline form, those forms are called allotropes; the two most common allotropes of carbon are diamond and graphite.The crystal structure of diamond is an infinite three-dimensional array of carbon atoms, each of which forms a structure in which each of the bonds makes equal angles with its neighbours.If the ends …
