Rhodium(III) and Ruthenium(II) Complexes with a Pentadentate Tetrapodal Phosphine Ligand

چکیده
Abstract Rhodium(III) and ruthenium(II) complexes supported by a pentadentate tetrapodal ( pentaPod ) phosphine ligand are synthesized through abstraction of one chloride from initially obtained κ 4 ‐ coordinated dichloro [MCl 2 ‐P Me PP Ph )] +/0 (M=Rh(III), Ru(II)) with alkali salts weakly coordinating anions. While for the rhodium 5 complex remaining, axial could not be replaced di‐ or triatomic ligands, in case ruthenium [Ru(CN)( ]Al(pftb) [Ru(N 3 )( 6 generated exchange. By comparison NMR parameters employing DFT calculations, additional insights into electronic influence different ligands (i. e., Cl − , CN N gained.

Synthesis, characterization and DFT studies of the cobalt(III) complex of a tetrapodal pentadentate N4S donor ligand.
The synthesis of the pentadentate ligand 2,6-bis(3,3-dimethyl-2,4-dioxocyclohexanyl)-4-thiaheptane (N4Samp) is described. The synthetic pathway involves the coupling of two 1,3-(dimethylenedioxy)-2-methyl-2-(methylene-p-toluenesulfonyl)propane moieties with sodium sulfide and subsequent synthetic elaboration to prepare the final N4S donor system. The cobalt(III) complex [Co(N4Samp)Cl]2+ has bee...

Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...
