WebWe would like to show you a description here but the site won’t allow us. WebThe crystal structure of diamond is equivalent to a face-centred cubic (FCC) lattice, with a basis of two identical carbon atoms: one at (0, 0, 0) and the other at (1/4, 1/4, 1/4), where the coordinates are given as fractions along the cube sides. This is the same as two interpenetrating FCC lattices, offset from one another along a body ...
WebWe found that for the BCC we had two elements included in the calculation of the structure factor with displacement vectors de = 0 and d2 = alî ++ 2)/2. For the FCC, there are four elements in the structure factor: d2 = 0 and d2 = a (*+)/4, dz = a (& + 2)/4, and d2 = alŷ + î)/4. WebStructure and bonding. Diamond has a giant covalent. structure in which: each carbon atom is joined to four other carbon atoms by covalent bonds; the carbon atoms have a regular lattice. arrangement;
