Stranded clusters: The treatment of (η3-propenyl)palladium chloride with a bulky, basic dinitrogen ligand in the presence of traces of water results in the formation of an unusual adamantanoid [{(η3-propenyl)Pd}6(μ3-OH)4] cluster (see picture). The clusters are linked into double strands through hydrogen bonds and bridging counterions.
