title: An unexpected semi-hydrogenation of a ligand in the complexation of 2,7-bispyridinyl-1,8-naphthyridine with Ru3(CO)12.
abstract: Thermal reaction of 2,7-bis(2-pyridinyl)-l,8-naphthyridine () with Ru3(CO)12 in the presence of moisture resulted in the formation of a formate-bridged diruthenium complex [(-H3)Ru2(μ-HCOO)(CO)4] (), in which the ligand was partially hydrogenated. Complex was fully characterized by spectroscopic analyses and X-ray single crystal determination. Regarding the partially reduced ligand in , it occurs through a water-gas shift type reduction. The bridging formate ligand can be substituted by other carboxylate ligands. Physical and chemical properties of the newly prepared complexes were investigated.
