Okay, I'lle make an abstract, and I will work on a name. I will be more
clear about what is meant by structural systems and that they are
stable, too:
Is what I mean is there are only three structural systems, the
tetrahedron, the octahedron, and the icosohedron. They are the only
stable solids, that is non-collapsing flex corners whose faces are
triangles. Most compounds are something other than these, like pentagons
with linear off shoots for example, that comprise the wrong number of
atoms to make a "solid" unit, and I mean solid as in the pythagorean
solids, the geometric term. Both methane and ammonia make different
variations of the tetrahedron, a pythagorean solid. --Ian

While you're at it learn about how people format their newsgroup
postings. Once you've done that please tell us why we should care that
certain shapes are geometrically spiffing (in an astronomical
context).
