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.
Contents
Example compounds
Diamond of course
- normal cubic diamond
- hexagonal diamond aka lonsdaleite.
Compounds with partial (e.g. 50%) substitution of carbon
- moissanite (this is gemstone grade transparent silicon carbide SiC)
- germanium carbide – (germanium is not too abundant)
- tin carbide – this one is not producible via thermodynamic means. Maybe it van be piezochemically mechanosynthesized.
Compounds made from other elements of the same group in the periodic table
- pure silicon
- pure germanium
- The oddball compound that is grey tin.
- ... lead rather not – it is too metallic
III-IV semiconductors
- boron nitride – Boron nitride (cubic c-BN and hexagonal w-BN) – not referring to it's graphitic polyporph h-BN
- aluminum phospide – Aluminium phosphide – this one is quite poisonous
- boron phospide – Boron phosphide
- aluminum nitride – Aluminium nitride
Other
- Checkerboard pattern neo polymorphs between group IV elements and III-IV semiconductors.
Diamondoid molecular building blocks
- 1,3,5,7-Hexamethylenetetramine | C6H12N4 – (wikipedia)
- 1,3,5,7-Tetraboraadamantane | C6H12B4 – (pubchem.ncbi.nlm.nih.gov)
These two have been proposed as bigger building blocks that may be easier to handle in a direct path approach. See: Lattice scaled stiffness.
- The integrated nitrogen atoms can form coordinate bonds to integrated boron atoms.
- the tetrahedral geometry (equal to an sp3 hybridized carbon – See: The basics of atoms) stays preserved.
(wiki-TODO: Find that proposal)
