Inversion-related chains are interlinked by C-H...pi interactions to form molecular layers parallel to the bc plane. These layers are interconnected through pi-pi interactions involving the five- and six-membered rings of the indole moiety.
RESUMO
A novel route for the conversion of (Bu4N)2[Ni(dmit)2] to (Bu4N)2[tto[Ni(dmit)2]] is reported here. This provides a much more efficient way of synthesizing (Bu4N)2[tto[Ni(dmit)2]] than the literature method. During the process, the conversion of dmit2- to tto2- was realized for the first time. This new synthesis should facilitate further research on the conducting bimetallic complexes [C]x[tto[Ni(dmit)2]]. In addition, a new crystal form of (Bu4N)2[tto[Ni(dmit)2]]. In addition, a new crystal form of (Bu4N)2[tto[Ni(dmit)2]] was determined by X-ray crystallographic analysis.
