Germanium is the most scarce element of the carbon group.
But it may be the most useful in advanced mechanosynthesis with …
- its tetra-valency and
- its bindnig strength that is neither to high as (as with carbon) or to low (as with lead or perhaps tin)
For advanced mechanosynthesis germanium is needed only in extremely low trace amounts. It's only needed on the tip of the tools. See the papers linked on the tooltip chemistry page. None of the surrounding machinery and structural framework in the nanofactory is likely to be critically dependent on germanium. So the low abundance of Germanium is not an issue.
As structural material
As a structural material it's rather unsuitable due to its low abundance.
It forms an oxidic mineral in with the tetragonal rutile structure called argutite
just as all the heavier elements of the group do (and silicon does under extreme conditions as seen in the mineral stishovite)
- Argutite GeO2 (Mohs 6-7; ~6.28g/ccm; tetragonal; rutile structure)
