Abstract
The temperature‐independent magnetic moment in complex 1 corresponds almost exactly to the spin‐only value of one unpaired electron per TiIII center, whereas 2 is diamagnetic. This is attributed to the fact that the [TiOTi]4⊕ unit in 1 is very likely linear, while in 2 it is bent (122.7°). Other than in 2 the d orbitals in 1 cannot overlap, and a spin‐spin coupling is therefore ruled out here (L = N,N′,N′‐trimethyl‐1,4,7‐triazacyclononane). equation imageKeywords
