We report the triply bridging coordination of thiophene and selenophene to a trinuclear metal cluster site. The triply bridging coordination of selenophene at a Pd3 site forms a unique spiro‐type Pd5 cluster. Furthermore, either thiophene or selenophene is accommodated stably at a Pd3 site supported by a backside μ3‐cyclooctatetraene ligand through the face‐capping μ3‐coordination. The Pd3 site supported by the cyclooctatetraene ligand showed higher binding affinity of benzene over thiophene, although a Pd2 site strongly favors thiophene over benzene.

Atmosphere. -A new NiZn-Pd nanocomposite catalyst containing highly stable divalent Pd species is developed. The intercalated anionic Pd hydroxide complex is rigidly fixed by the strong electrostatic interactions characteristic of NiZn. This system acts as an efficient heterogeneous catalyst for the oxidation of alcohols under an air atmosphere, without the need for any additive. Benzylic alcohols bearing electron-withdrawing substituents such as (Ic) only give poor yields. -(HARA, T.; ISHIKAWA, M.; SAWADA, J.; ICHIKUNI, N.; SHIMAZU*, S.; Green
