Graphical Abstract
Gut verschachtelt: Die ersten σ-Organoniob-Verbindungen mit den Zusammensetzungen [NbIIIR4]− und NbIVR4 werden vorgestellt. Die Nb-Zentren der [Nb(C6Cl5)4]q−-Einheiten (q=0, 1) befinden sich in einer triakistetraedrischen Umgebung, die von einem inneren NbC4- (siehe Bild, grau) und einem äußeren NbCl4-Tetraeder (grün) erzeugt wird.

- 22From the analysis of the isothermal magnetization results (Figure 4) as well as from the linear dependence of 1/χ(T) over the whole temperature range (Figure S1a), an upper limit for the zero-field splitting of approximately 50 GHz can be obtained for the non-Kramers system 1. Following this estimate, EPR spectra would be expected to be observable as in the VIII case (see Ref. [12]), at least in Q band. Our failure to observe any EPR spectrum for 1 would thus not be related to the energy of the transitions involved, but rather to experimental broadening of the signals, possibly arising from manifold distribution of paramagnetic centers in the bulk sample.
