This article is a stub. It needs to be expanded.

Compounds which

  • (1) fall under the class of gemstone like compounds and
  • (2) have a crystal structure similar to diamond (cubic and hexagonal)

Sometimes "diamondoid" refers to just (1). In this wiki though both will be required to be true (starting 2021-06).

Note that mixes between cubic and hexagonal are possible (along one spacial dimension) by choice of "stacking order". Mechanosynthesizing such cubic hexagonal switches in more than one dimension leads to at least controlled atomically precise line like one dimensional faults.

Example compounds

Diamond of course

Compounds with partial (e.g. 50%) substitution of carbon

Compounds made from other elements of the same group in the periodic table

III-IV semiconductors

Other

  • Checkerboard pattern neo polymorphs between group IV elements and III-IV semiconductors.
