text: Subdivisions of inorganic chemistry are numerous, but include:
  *organometallic chemistry, compounds with metal-carbon bonds. This area touches on organic synthesis, which employs many organometallic catalysts and reagents.
  *cluster chemistry , compounds with several metals bound together with metal-metal bonds or bridging ligands.
  *bioinorganic chemistry, biomolecules that contain metals.  This area touches on medicinal chemistry.
  *materials chemistry and solid state chemistry, extended (i.e. polymeric) solids exhibiting properties not seen for simple molecules.  Many practical themes are associated with these areas, including ceramics.
