Steric influence of salicylaldehyde-based Schiff base ligands on the formation of: Trans-[Re(PR3)2(Schiff base)]+ complexes

Complexes of the type trans-[Re(PR3)2(Schiff base)]+ (R = ethyl and/or phenyl) 2-7 were prepared by the reaction of (nBu4N)[ReOCl4] with H2sal2en or H2sal2ibn followed by addition of a tertiary phosphine. The trans-[Re(PR3)2(sal2en)]+ complexes 2-4 were stable in solution, whereas the trans-[Re(PR3)2(sal2ibn)]+ complexes 6-7 were observed to convert to their corresponding cis-[ReO(PR3)(sal2ibn)]+ products through a process involving ligand dissociation, metal oxidation, and Schiff base ligand rearrangement. The conversion of the trans-[Re(PR3)2(sal2ibn)]+ complexes is likely driven by steric interactions between the bulky backbone gem-dimethyl groups of the sal2ibn ligand and the phosphine ligands. These complexes were isolated and characterized by 1H and 13C NMR, FT-IR spectroscopy, cyclic voltammetry, and single crystal X-ray diffraction. The results reported herein provide insight into the factors that drive trans-[Re(PR3)2(Schiff base)]+ complex formation. This will aid in the development of novel 186/188Re therapeutic agents and the design of novel bifunctional N2O2 Schiff base ligands.

New compounds of tetradentate Schiff bases with vanadium(IV) and vanadium(V)

A new range of potentially tetradentate proligands, H2L, derived from aromatic aldehydes and ketones and aliphatic diamines has been prepared. Their vanadyl(IV) and vanadyl(V) complexes [VO(L)] and [VO(L)]+, and also some adducts [VO(L)→VO(L)]+, have been synthesized. The structures of four selected complexes have been determined and it is shown that these must be a result of both steric and electronic factors that make prediction of conformation and stacking difficult. The adducts [VO(L)→VO(L)]+ have structures that persist in solution in dichloromethane, where they can undergo redox chemistry, but they apparently dissociate into their component complexes in the donor solvent acetonitrile.
