Supramolecular aggregation of Pd6Cl12, a cluster of comparable size to fullerene, with aromatic donors and with C60

The crystallization of solids that are composed of several combinations of inorganic halides were analyzed after reacting with Pd6Cl2 and aromatic hydrocarbons. The polymorphic alpha-form PdCl2 have infinite and linear chains of palladium units that are coordinated by four chlorine atoms with double bridges. The beta-form of PdCl12 is isomorphic with discrete molecules of Pd6Cl12. Pd6Cl12 has a similar geometric configuration to Pt6Cl12 and related transition metal clusters that possess an octahedral array of metal atoms with twelve edge-bridging halogen atoms.
