| The great variety of rigid shapes of higher diamondoids
makes them attractive structural components for molecular-design
applications. Below is an image gallery of our higher diamondoid structures:

pentamantane higher diamondoid crystals as found in oil (mostly
in condensates associated with gas). A gallon of condensate
yields a spoonful or two of crystals. Each diamondoid is one
billionth of a billionth of a carat — impossible to see with the
naked eye. |
Diversity of Molecular Geometries
Examples of higher diamondoid molecular structures from
tetramantanes through undecamantanes.
Note some structures are enantiomeric. Structure #50 is an alkylated pentamantane.
