Abstract:
An unusual structure is found for a novel triangulo palladium cluster, stabilized by 2,4,6-triphenylphosphine and triethylphosphane (see figure; large open circles: Pd, small hashed circles: P, small open circles: C). The bonding involving phosphinine bridges between two Pd atoms is based on σ and π orbital interactions, as demonstrated by quantum-mechanical calculations of a model compound.
