What’s New in Name Version 2023

Version 2023 of Name improves naming of coordination structures, allows users to indicate polyhedral configurations, and includes new principles of enclosing of simple substituents without locants. Read below for details, and contact us for help upgrading your software.

Updated Rules for Substituents without Locants

Name’s principles for enclosing (i.e., adding brackets around) substituents without locants has been updated according to recent changes in IUPAC recommendations. All substituents, beyond the first without locants, will now be enclosed.

Previously: tert-butyl(ethoxy)dimethylsilane cyclohexyl(hydroxy)phenylacetic acid
Now: tert-butyl(ethoxy)di(methyl)silane cyclohexyl(hydroxy)(phenyl)acetic acid

Better Name Generation for Coordinated Structures

Name generation for coordinated structures better follows IUPAC inorganic nomenclature recommendations.

Previously: (aniline)(ethane-1,2-diolato-κO1)(methoxymethane)
Now: (aniline-κN)(2-hydroxyethanolato-κO)[(methoxy-κO)methane]

Polyhedral Configuration Naming

You can now generate names that include stereoconfiguration for square planar, tetrahedral, trigonal pyramidal, and octahedral configuration. Recognition is based on the configuration defined with stereobonds.


Examples of names that include the polyhedral configuration.

Name also includes ChemSketch. We’ve improved features for this as well:

Enhanced Number Formatting

You can now use atom numbers that include italic, subscript, superscripts, or Greek characters.


Distinguish Coordination Bonds from Stereobonds for Inorganics and Organometallics

Coordination bonds are now dotted bonds to distinguish them from the dashed bond that indicates down stereochemistry.

Previously Now

In the new structure, dotted lines indicate coordination and dashed lines indicate a stereochemical bond.
