Synthesis and molecular structure of [K(18-crown-6)][(CO)4FePPh2CS2]
Abstract
[K(18-crown-6)][(CO)4FePPh2]1 reacts with CS2 to produce the adduct [K(18-crown-6)][(CO)4FePPh2CS2]2 in high yield; an X-ray diffraction analysis confirms the phosphorus coordination of the PPh2CS2– ligand in 2 and shows weak contacts between the sulfur atoms and the potassium ion of the crown ether.
