Large shortening of the lead-lead bond in a diplumbyne upon its one-electron reduction

Key Points

• The study aims to investigate the effects of one-electron reduction on the structure of diplumbyne.
• Performed one-electron reduction using KC8 and 18-crown-6.
• Produced crystals of the resulting radical anion.
• Analyzed the structure using X-ray crystallography.
• Significant shortening of the lead-lead bond observed in the radical anion.
• Confirmed formation of the [K(18-crown-6)][AriPr6PbPbAriPr6] salt.
