Pentacoordinate Nitrogen Structures from Cambridge Database

A Cambridge Structural Database (CSD) search identified only three crystal structures containing pentacoordinate nitrogen. This dataset was compiled by Henry S. Rzepa of Imperial College London to explore a hypothesis analogous to a recently confirmed hexacoordinate carbon structure. The data originates from a published proposal and references a specific crystal structure deposit (DOI:10.5517/CCDC.CSD.CC1M71QM).

Use Cases

• Identify pentacoordinate nitrogen environments by analyzing CSD search results and atomic coordinates.
• Compare bond lengths and angles in pentacoordinate nitrogen structures to theoretical predictions.
• Validate new synthetic targets for high-coordination nitrogen compounds using existing crystallographic data.

Strengths

• Data is sourced from the authoritative Cambridge Structural Database (CSD).
• References a specific, confirmed crystal structure for hexacoordinate carbon (DOI:10.5517/CCDC.CSD.CC1M71QM).

Limitations

• Extremely small sample size, with only three identified structures containing pentacoordinate nitrogen.
• Dataset scope and available features (rows, columns) are not specified in the description.
