Hexaarylcyclotriplumbane: A Molecule with a Homonuclear Ring System of Lead

The reaction of lead(II) bromide with RMgBr, R = 2,4,6-Et3C6H2, furnishes black crystals of hexakis(2,4,6-triethylphenyl)cyclotriplumbane (1) as the first molecule with a homonuclear lead ring. 1 adopts a skewed structure with highly stretched Pb−Pb bond lengths of 3.185 Å (average), which indicate...

Zusammenfassung:	The reaction of lead(II) bromide with RMgBr, R = 2,4,6-Et3C6H2, furnishes black crystals of hexakis(2,4,6-triethylphenyl)cyclotriplumbane (1) as the first molecule with a homonuclear lead ring. 1 adopts a skewed structure with highly stretched Pb−Pb bond lengths of 3.185 Å (average), which indicate that the three-membered ring is formed by weak interactions of 3 singlet plumbylene molecules.
