title: New metal-only Lewis pairs: elucidating the electronic influence of N-heterocyclic carbenes and phosphines on the dative Pt-Al bond.
abstract: The synthesis and full characterization of a new heteroleptic N-heterocyclic carbene (NHC)-phosphine platinum(0) complex and formation of its corresponding alane adduct is reported. The influence of the ligands on the Lewis basic properties was studied via multinuclear NMR-spectroscopy, X-ray analyses, and density functional theory (DFT) calculations. Consistently, the effect of changing the halogens upon the Lewis acid properties of aluminum halides was studied by X-ray analysis and DFT calculations.
