Seven gold(I) N-heterocyclic carbene (NHC) complexes were synthesized, characterized, and identified as suitable precursors for focused electron beam-induced deposition (FEBID). Several variations on the core Au(NHC)X moiety introduced, that is, of NHC ring (imidazole or triazole), alkyl N-substituents (Me, Et, iPr), ancillary ligand X (Cl, Br, I, CF 3 ). The seven tested FEBID in an on-substra...
The field of asymmetric catalysis is rapidly developing and the chiral ligands play a key role in enantioselective transition‐metal catalysis. electron‐rich N ‐heterocyclic carbenes (NHCs) have established themselves as popular class stereodirecting ancillary to catalyze organic transformations more efficient ways. Several novel complexes combination with tailored ligand design emerged during l...
N -tert -butyliminodiacetic acid (H2TEBIDA, compound 1) has been prepared and characterised by thermogravimetric analysis, FT-IR and NMR spectra, and X-ray crystallography (final R1 /0.04). The zwitterion H2TEBIDA 9 is intra -stabilised by a hydrogen bond, and H-bonded chains of zwitterions form supramolecular 2D bilayers with tert -Bu groups towards the external faces. Compounds [Cu(TEBIDA)(H2...
Two isostructural series of trigonal prismatic complexes, M(Bp(Me))3 and M(Bc(Me))3 (M = Y, Tb, Dy, Ho, Er, U; [Bp(Me)](-) = dihydrobis(methypyrazolyl)borate; [Bc(Me)](-) = dihydrobis(methylimidazolyl)borate) are synthesized and fully characterized to examine the influence of ligand donor strength on slow magnetic relaxation. Investigation of the dynamic magnetic properties reveals that the obl...
