Metal clusters diamagnetic behavior

All characterized Pd(I) compounds have Pd-Pd or Pd-M bonds. Accordingly, the paramagnetic behavior anticipated for a d configuration is not found in these multinuclear diamagnetic complexes as the expected unpaired electron is in fact involved in the formation of a metal-metal bond. There are some palladium clusters in formal oxidation states ranging from 0 to -1-1 (metal-metal bonds do not count in the assignment of oxidation states) that will be considered here.
