|Molar mass||65.09 g/mol|
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
The structure shown is a composite of five resonance contributors in which each carbon atom carries part of the negative charge.
Salts of the cyclopentadienyl anion can be stable, e.g., sodium cyclopentadienide.
