Synthesis and X-ray Crystal Structure of Bis{2,4,6- tris[bis(trimethylsilyl)methyl]phenyl}dibromoplumbane: The First Monomeric Diorganodihaloplumbane in the Crystalline State

Reaction of a plumbylene Tbt 2 Pb: ( 1 ) with carbon tetrabromide in THF gave the first crystallographically characterized dibromoplumbane Tbt 2 PbBr 2 ( 2 ) bearing two 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt) groups. The X-ray crystallographic analysis revealed that 2 has a monomeric structure with a distorted tetrahedral lead center.
