Abstract
The reactions of the 3-coordinated metal tris-(bis-trimethylsilylamides) M[N(SiMe 3) 2] 3 (ML 3; where M = La, Pr, Eu, Gd and In) with trimethylphosphineoxide Me 3PO(L′) have been studied. All of these metals gave 1:1 complexes ML 3(L′) which dissociated on heating in vacuo. The Pr and Eu complexes gave interesting pseudo-contact shifted 1H NMR spectra which are qualitatively in accord with the expected molecular structure. Variable temperature NMR measurements proved the restricted rotation of the silylamide (L) ligands occurs around the M–N axes. Evidence is also presented for unstable 5-coordinated complexes ML 3(L′) 2. The gadolinium 1:1 complex gave a very broad NMR spectrum and its ESR spectrum is being investigated.
