Abstract
2,7 –Bis(2-pyridyl)-1,8-naphthyridine (bpnp) is a multiple pyridinyl nitrogen donor, which is capable of binding with metal ions in a chelating manner. In case of coordination with two metal ions, these centers are in close distance to have metal-metal interactions, which raises a subject of considerable interest. In our work, we tried to synthesize the dipalladium complex with bpnp. Indeed, we have successfully obtained a palladium complex chelated with bpnp, but in a trimetallic form. The structure of the complex is revealed by X-ray single crystal analysis.
For the first time, a mixed valence tripalladium species is constructed from the complexation of Pd(0), Pd(II) and bpnp. Detail structural formulation via X-ray diffraction analysis confirms the coordination mode. This tri-palladium complex was found to have catalytic activity on hydroxylation or reduction of phenylboronic acids
