Seven-coordinate mixed-ligand tungsten(II) chelates containing carbonyls, triphenylphosphine, and 8-quinolinolato, picolinato or a quadridentate schiff-base
The complexes W(CO)2(PPh3)(q)2, W(CO)2(PPh3)(pic)2 and W(CO)2(PPh3)(dsp) (where Ph = C6H5, q− = 8-quinolinolato, pic− = picolinato, and dsp2− = the anion of the Schiff-base N,N′-disalicylidene-1,2-phenylene-diamine) have been synthesized. The physical properties of these complexes are indicative of seven-coordinate mixed-ligand tungsten(II) chelates. W(CO)2(PPh3)(pic)2 is the most photochemically reactive and W(CO)2(PPh3)(q)2 is the most thermally reactive. Evidence that the steric effects of the quadriadentate dsp2− ligand cause a change in the overall seven-coordinate sterochemistry is presented.
