Deprotonation of i PrATH [ i PrAT = 2‐(isopropylamino)troponate] with an excess of n BuLi resulted in the hexameric lithium 2‐(isopropylamino)troponate complex [( i PrAT)Li] 6 . In the solid state the hexameric core can be understood as two six‐membered Li 3 O 3 rings, which are tied together by the aminotroponate moieties. Further reaction of [( i PrAT)Li] 6 with YbCl 3 in a 1:2 stoichiometric ratio gave the dimeric complex [( i PrAT) 3 Li 2 Cl 2 Yb] 2 , in which the two [( i PrAT) 3 Yb] subunits are bridged by four LiCl units. In the center of this unusual compound an Li–Cl–Li–Cl square is located. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
