“…[18] Even PdA C H T U N G T R E N N U N G (dppe) complexes with mono-anionic dithiocarbamato ligands show shorter PdÀS bonds (range = 2.323-2.338 ). [19] We attribute this difference to the large bite angle in metalla-acetylene dithiolate complexes (S1 À S2 = 3.359 in 13 and 3.391 in 14 + ), whereas S À S distances of 3.0-3.1 are typical for dithiolene ligands. [20] Obviously, the change of the overall complex charge on going from 13 to 14 + only marginally affects the bonding parameters at Pd.…”

A series of heterodinuclear complexes with acetylene dithiolate (acdt(2-) ) as the bridging moiety were synthesised by a facile one-pot procedure that avoided use of the highly elusive acetylene dithiol. Generation of the W-Ru complex [Tp'W(CN)(CO)(C2 S2 )Ru(η(5) -C5 H5 )(PPh3 )] (Tp'=hydrotris(3,5-dimethylpyrazolyl)borate) and the W-Pd complexes [Tp'W(CN)(CO)(C2 S2 )Pd(dppe)] and [Tp'W(CO)2 (C2 S2 )Pd(dppe)][PF6 ] (dppe=1,2-bis(diphenylphoshino)ethane), which exhibit a [W(η(2) -κ(2) -C2 S2 )M] core (M=Ru, Pd), was accomplished by using a transition-metal-assisted solvolytical removal of the Me3 Si-ethyl thiol protecting groups. All intermediate species of the reaction have been fully characterised. The highly coloured W-Ru complex [Tp'W(CN)(CO)(C2 S2 )Ru(η(5) -C5 H5 )(PPh3 )] shows reversible redox chemistry, as does the prototype complex [Tp'W(CO)2 (C2 S2 )Ru(η(5) -C5 H5 )(PPh3 )][PF6 ]. Single crystal X-ray diffraction and IR, EPR and UV/Vis spectroscopic studies in conjunction with DFT calculations prove the high electronic delocalisation of states over the acdt(2-) linker. Comparative studies revealed a higher donor strength and more pronounced dithiolate character of acdt(2-) in [Tp'W(CN)(CO)(C2 S2 )Ru(η(5) -C5 H5 )(PPh3 )] relative to [Tp'W(CO)2 (C2 S2 )Ru(η(5) -C5 H5 )(PPh3 )](+) . In addition, the influence of the overall complex charge on the metric parameters was investigated by single-crystal X-ray diffraction studies with the W-Pd complexes [Tp'WL2 (C2 S2 )Pd(dppe)] (L=(CN(-) )(CO) or (CO)2 ). The central [W(C2 S2 )Pd] units exhibit high structural similarity, which indicates the extensive delocalisation of charge over both metals.

Regiospecific Remote Pt–H Interactions in Oligomethylene‐Vaulted (N^{^}C^{^}N)‐Pincer Pt^II Complexes

(N^C^N)‐Pincer type bis(iminomethyl)phenylPtII complexes 1 and 2 having a macrocyclic vaulting structure consisting of deca‐ undeca‐, and dodecamethylene bridges were synthesized and subsequently characterized by NMR, IR spectroscopy, mass spectrometry, and single‐crystal XRD. Unprecedented remote intramolecular Pt–H interactions were observed on the linker hydrogen atoms at β‐and ζ‐positions in a highly regiospecific manner both in the crystal and solution states. The hydrogen bonding nature, originating from overlap between Pt dz² and σ* of the specific C–H bonds, was revealed by NBO analysis of 1 on the basis of dispersion‐corrected DFT calculations.

The complexes [Ni 2 (L) 2 ] 2 ·H 2 O (1) and [Cu 2 (L) 2 (H 2 O)]· 2CH 3 OH (2) were prepared by reaction of the chiral Schiff base ligand N-[(1R,2S)-2-hydroxy-1,2-diphenyl]-acetylacetonimine (H 2 L) with Ni II and Cu II ions, respectively, aiming to develop economically and environmentally-friendly catalysts for the hydrogenation of ketones. They have a dinuclear skeleton with axial vacant sites. The catalytic effects of the two complexes for hydrogenation of ketones were tested using dihydrogen gas as hydrogen source. They present some catalytic
