TETRAHEDRANEITES & BOROTETRAHEDRANEITES

Replacing the atomic sites in the C diamond polytypes with tetrahedrane-like sites...one would get the corresponding tetrahedraneites. Also the B-Cl molecular structure is comprised of a borotetrahedrane-like B-4 substructure, which could be the basis for borotetrahedraneite patterns patterned on the diamond polytypes as B allotropes. I wonder if any of these patterns or allotropes is real or could be real as nanocrystals or microcrystals or macrocrystals.
