The chemistry of metals with small organic molecules (called Ligands) is
called Organometallic chemistry. Abstraction of metals from their ores 
is placed in Inorganic chemistry texts. Generally metal chemistry is not 
placed in physical chemistry headings. Structural properties of their crystal
structures would be found in both Inorganic and Physical texts.

Yes you are correct in that stereochemistry is not restricted to organic 
compounds. In fact molecules are three dimensional physical bodies having a
specified mass. The reason for your confusion is that you do not know how 
chemists are trained. They take courses with titles like Organic, Analytic,
Inorganic, Physical. In each course you are introduced to different topics.
Of course you are expected to remember each one :)
By the way an advanced course where stereochemistry returns is group theory.
