DIAMOND is generally thought to be one of the most perfect crystals occurring naturally: its atomic structure ... of the crystal were arranged on two interpenetrating face-centred cubic lattices ...

The crystal has a lattice parameter of 0.541 nm. The crystal structure is also known as diamond cubic and may be thought of as two interpenetrating fcc lattices, one for sulphur the other for zinc, ...

It melts at 3727 C. The stable form of carbon at room temperature is Graphite which has a hexagonal crystal structure. (Top diagram) Diamond is metastable at room temperature and has a diamond cubic ...

To create BC8, an eight-atom body-centered cubic crystal exhibiting a 30% greater ... shape of the four nearest neighbor atoms in the diamond structure perfectly matches the optimal configuration.
