The B16 (GeS)
Structure
Last modified 5 April

You can now
Pearson says that this
structure is a distorted NaCl (B1) structure.
So far I haven't found the magic values of the parameters that makes
this so.
You may be wondering what the difference is between this
structure and the B27 (FeB) structure. You
are entitled.
This structure was suggested for inclusion by Dr. Soon-Ku Hong of
Samsung.
