Indenyllithium·2(N,N,N′-trimethylethylenediamine)]∞: N–H hydrogen bridges to the indenyl anion

Abstract

The crystal structure of the title compound, bis(N,N,N′-tri­methyl­ethyl­enedi­amine)­lithium indenide, [Li(C5H14N2)2](C9H7), forms discrete layers of cations and anions, with N—H⋯C hydrogen-bond interactions between these layers. Both the cation and anion exhibit a crystallographic centre of inversion. This leads to a twofold disorder of the anion.
