Crystal structure of dimethyl-1κ2C-bis(μ-4-methylphenolato-1:2κ2O:O)(N,N,N′,N′-tetramethylethylenediamine-2κ2N,N′)indium(III)lithium(I)

Abstract

The mixed bimetallic title compound, [InLi(CH3)2(C7H7O)2(C6H16N2)] or [(tmeda)Li-μ-(4-MeC6H4O)2InMe2] (tmeda isN,N,N′,N′-tetramethylethylenediamine), exhibits a four-membered LiO2In ring coreviabridging 4-methylphenolate groups. The Li and In atoms are in distorted tetrahedral N2O2and C2O2bonding environments, respectively. The Li atom is further chelated by a tmeda group, yielding a spirocyclic structure.
