TLDR
In this paper, the analysis of the 13C n.m.spectra of indene and some indene π-complexes allows to distinguish between h6-, h5-, and h3-compounds.Abstract:
Die Analyse der 13C-NMR-Spektren von Inden und einigen π-Komplexen des Indens erlaubt, zwischen h6-, h5- und h3-Verbindungen zu unterscheiden. Insbesondere wird die Struktur von Bis(h3-indenyl)nickel geklart und uber eine verbesserte Synthese dieser Verbindung berichtet.
13C N.M.R. Spectra of Indene π-Complexes and their Use for the Determination of Ligand Haptoproperties
The analysis of the 13C n.m.r.spectra of indene and some indene π-complexes allows to distinguish between h6-, h5-, and h3-compounds. In particular the structure of bis(h3-indenyl)-nickel is determined and an improved synthesis of this compound is reported.read more

TL;DR: In this article, the splitting pattern observed for the 13 C NMR signals in the 1 H-undecoupled spectra of symmetrically ortho-disubstituted benzenes differs characteristically for carbons in the position α and β to the substituted carbons, thus, giving rise to typical fingerprints.
