Kw. Hellmann et al., AGGREGATION OF LITHIUM AND MIXED THALLIUM(I)-LITHIUM AMIDES THROUGH ETA(3)-PI-ARENE AND ETA(6)-PI-ARENE INTERACTIONS IN THE SOLID, Chemical communications, (5), 1998, pp. 549-550
The mixed Li-Tl amide [C10H6{N[Li(thf)(2)]SiMe3}{N(Tl)SiMe3}] has been
synthesized and shown to aggregate via eta(6)-arene-thallium coordina
tion in the solid; a related pattern of aggregation is found for the p
artially solvated homometallic Li amide [C10H6{N[Li(thf)]SiMe3}{N(Li)S
iMe3}] which displays an unusual eta(3)-arene-lithium interaction.
