Inclusion of an iodine molecule in a tiara-like octanuclear palladium thiolate complex

Abstract

An iodine molecule was successfully inserted into the inner cavity of a tiara-like octanuclear palladium thiolate complex, [Pd(μ-SCH2CO2Me)2]8. The included iodine molecule coordinated weakly to six palladium atoms in both linear and bent modes, as confirmed by X-ray crystallography and DFT calculations. The inclusion complex reacted with an excess amount of I2 to produce a disulfide, which was accompanied by decomposition of the tiara ring.
