iodine in diethyl ether

iodide in water in neutral or weakly alkaline H2O;;

in toluene a toluene soln. of Pt-complex was added to a soln. of mercurate in toluene, mixt. was kept in a sealed evacuated ampoule at 20°C for 15 h; crystals of (C6H6)2CrI were sepd. (identified by IR, ESR spectral data and melting point), soln. was concd., hexane added to give crystals of HgPt-complex (identified by LSC analysis and IR spectroscopy);
