Abstract

Palladium-filled sandwiches: The reaction between the [Os10(μ6-C)(CO)24]2- ion and [Pd(NCMe)4](BF4)2 yields the osmiumpalladium mixed-metal cluster, [{N(PPh3)2}2{Os18 Pd3(μ6-C)2(CO)42}], which has the highest nuclearity known for such clusters, and has been shown by single-crystal X-ray analysis to be a "metal sandwich" with two Os9 units connected by a triangular Pd3 subcluster (see picture); five reversible cathodic waves have been observed through cyclic voltammetry.
