12/6/2018 Quiz 07 - Crystal Structures - Part 1: Mat E 273 The reduced-sphere depiction of the diamond cubic (DC) unit cell is provided below. Note that bonds within the cube are colored to highlight the tetrahedral coordination associated with sp bonding. The dotted lines merely show the cubic symmetry that this packing scheme also features, but these are not indicating covalent bonds. The radius of atoms that pack in DC fashion are related to the lattice parameter by the relation: What is the linear packing factor (LPF) of <110> directions in DC ? 3
