Publikováno v: Inorganic Chemistry. 56:15119-15129

Single-molecule magnets (SMMs) retain a magnetization without applied magnetic field for a decent time due to an energy barrier U for spin-reversal. Despite the success to increase U, the difficult to control magnetic quantum tunneling often leads to

Synthesis and characterisation of bulky guanidines and phosphaguanidines: precursors for low oxidation state metallacycles

Autor: Richard P. Rose, Cameron Jones, Guoxia Jin, Kai-Alexander Lippert, Peter C. Junk, Andreas Stasch

Publikováno v: New J. Chem.. 33:64-75

Reactions of alkali metal amides or phosphides with the bulky carbodiimide, ArNCNAr (Ar = C6H3Pri2-2,6), followed by aqueous work-ups, have yielded several guanidines, ArNC(NR2)N(H)Ar (R = cyclohexyl (GisoH) or Pri (PrisoH); NR2 = cis-NC5H8Me2-2,6 (P

Homoleptic lanthanide(ii)–bis(guanidinate) complexes, [Ln(Giso)2] (Giso = [(ArN)2CN(C6H11)2]−, Ar = C6H3Pri2-2,6): planar 4-coordinate (Ln = Sm or Eu) vs distorted tetrahedral (Ln = Yb) geometries

Publikováno v: Dalton Trans.. :187-189

The first homoleptic lanthanide(II)-guanidinate complexes have been prepared and shown to have differing coordination geometries (including unprecedented examples of planar 4-coordination) that depend on the size of the lanthanide metal.

Electronic and Molecular Structures of Heteroradialenes: A Combined Synthetic, Computational, Spectroscopic, and Structural Study Identifying IR Spectroscopy as a Simple but Powerful Experimental Probe

The vicinity of a hydrogen bond donor (O-H) and a hydrogen bond acceptor (C=O or C=N- R) in salicylaldehydes and ortho-Schiff bases results in significant structural variations compared to the monosubstituted derivatives that are reflected in the ele
