Stability Constants and Thermodynamic Functions for Crown Ether-Metal Complexes, 1971-2000

A critical evaluation of stability constants and thermodynamic functions for metal complexes of three specific crown ethers across multiple solvents, published between 1971 and 2000. The dataset, compiled by Françoise Arnaud‐Neu of the Centre National de la Recherche Scientifique, includes data for alkali, alkaline earth, and select heavy metal ions. Published values are categorized as 'accepted' or 'rejected', with accepted values further classified as recommended, provisional, or recommended based on single-group reliability.

Use Cases

• Predicting metal ion selectivity of crown ethers based on stability constants across different solvents.
• Training thermodynamic models for complex formation using accepted enthalpy and free energy data.
• Benchmarking computational chemistry methods against critically evaluated experimental binding constants.
• Analyzing the effect of solvent polarity on complex stability for alkali and alkaline earth metal ions.

Strengths

• Data is critically evaluated, with each entry categorized as 'accepted' or 'rejected' based on defined quality criteria.
• Covers three well-defined crown ethers (12C4, 15C5, 18C6) and a specific set of metal ions across nine solvents and their mixtures.
• Includes a defined temporal scope, aggregating research published over a 29-year period from 1971 to 2000.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Last update date is unknown; data is over two decades old and may not reflect recent research.
• The dataset's license is listed as closed, which may restrict redistribution or commercial use.
