Syntheses, Characterization and Theoretical Investigation of Two Coordinate Palladium(0) and Platinum(0) Complexes Utilizing π-accepting Carbenes.
Abstract: π-Accepting cyclic alkyl(amino) carbenes were employed for the preparation of two coordinate and bent palladium(0) and platinum(0) complexes. The palladium complex exhibits crystallochromism (from maroon to green) due to controlled bending of C-Pd-C bond angle by ~ 6° during the elimination of a lattice solvent molecule. The bonding and stability of these complexes are studied by theoretical calculation.
