4,4′-Bipyridine (abbreviated to 4,4′-bipy or 4,4′-bpy) is an organic compound with the formula (C 5 H 4 N) 2. It is one of several isomers of bipyridine . It is a colorless solid that is soluble in organic solvents.
Bipyridines are a family of organic compounds with the formula (C 5 H 4 N) 2, consisting of two pyridyl (C 5 H 4 N) rings. Pyridine is an aromatic nitrogen-containing heterocycle. The bipyridines are all colourless solids, which are soluble in organic solvents and slightly soluble in water. Bipyridines, especially the 4,4' isomer, are mainly of ...
Pyridine-borane (C 5 H 5 NBH 3, melting point 10–11 °C) is a mild reducing agent. structure of the Crabtree's catalyst. Transition metal pyridine complexes are numerous. [108] [109] Typical octahedral complexes have the stoichiometry MCl 2 (py) 4 and MCl 3 (py) 3. Octahedral homoleptic complexes of the type M(py) + 6 are rare or tend to ...

2,2′-Bipyridine (bipy or bpy, pronounced / ˈ b ɪ p iː /) is an organic compound with the formula (C 5 H 4 N) 2. This colorless solid is an important isomer of the bipyridine family. It is a bidentate chelating ligand, forming complexes with many transition metals. Ruthenium and platinum complexes of bipy exhibit intense luminescence. [1]
Complexes of phen and those of 2,2'-bipyridine (bipyr) are similar: the metal-ligand ensemble is planar, which facilitates electron delocalization. As a consequence of this delocalization, phen complexes often exhibit distinctive optical and redox properties.
