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.

Abstract

One-electron reduction of the diplumbyne AriPr6PbPbAriPr6, 1, with KC8 in the presence of 18-crown-6 affords crystals of the salt of its radical anion, K(18-crown-6)AriPr6PbPbAriPr6, 2, AriPr6 = C6H3-2,6-(C6H2-2,4,6-iPr3)2. Its X-ray...
