Abstract

The lead(I) dimer [Pb( _t _BuAm ^Dipp)] ₂ ([ _t _BuAm ^Dipp] ^– = [tBuC{NDipp} ₂] ^–, Dipp = 2, 6-iPr ₂C ₆H ₃) was formed as a side product during the reaction of the aluminyl anion [K{Al(NON)}] ₂ ([NON] ² ^– = [O{SiMe ₂NDipp} ₂] ² ^–) and the plumbylene [Pb( _t _BuAm ^Dipp)Cl] ₂. Herein, we report the solid-state and electronic structure of this hitherto unknown Pb(I) complex.
