Polymers
Polymer structures cannot be expressed by SMILES. However, Struct>Name supports many homopolymers, copol-
ymers and alternating polymers. For example:
Figure 8.4: polyaziridine compound with sulfamic acid (1:1)
Other compounds
Phosphorous and Arsenic compounds
Si, Ge, Sn, and Pb compounds
Boron compounds
Organometallic compounds
Struct>Name generates names with proper CIP stereochemistry descriptors.
Struct>Name provides direct support for stoichoimetry specified as bracket properties, including fractional stoi-
chiometry. Also, the manner in which the stoichiometry of 0.5 ("hemi") and 1.5 ("sesqui") is handled has also been
improved. For example:
Figure 8.5: 2-(aminooxy)acetic acid hemihydrochloride
Struct>Namefollows IUPAC rules as closely as possible when generating chemical names.. However, while han-
dling indicated hydrogens, it conforms to CAS nomenclature recommendations. For example, the carbon atom
between two oxygen atoms in 1,3-dioxole can never form double bonds as its two neighbors (oxygen atoms) have no
free valences. While preferred IUPAC (PIN) name for that structure is 2H-1,3-dioxole, Struct>Name generates the
name 1,3-dioxole. The name produced by Struct>Name conforms to CAS nomenclature recommendations in this
regard.
Unsupported structures
This feature has a few limitations for interpreting some structures such as:
