What is bpy in chemistry?

Wikipedia. License. 2,2′-Bipyridine (bipy or bpy, pronounced ) is an organic compound with the formula C10H8N2. This colorless solid is an important isomer of the bipyridine family. It is a bidentate chelating ligand, forming complexes with many transition metals.

Is bpy neutral?

Since bipyridine is a neutral ligand, it forms charged complexes with metal cations for which it is used in the design and synthesis of metal-bipyridine complexes.

What is the molecular formula of 2 2 bipyridine?

C10H8N22,2′-Bipyridine / Formula

What is the charge on bipyridine?

Further, because bpy is neutral, the charge of the metal ion is retained and the metal-bpy complex does not require modification for aqueous solubility (Fig. 13).

Is bipyridine a pi acceptor?

cyanogen, NC-CN). Charge donation into such systems results in stabilization, therefore bipyridine is found among the pi-acceptor ligands.

Is Bpy strong field?

2,2′-Bipyridine is a strong field ligand that forms relatively stable complexes, with the inherent M–N bond strength enhanced by the chelate effect.

What is the chemistry of bipyridine coordination?

The versatility of bipyridine has inspired numerous studies of its coordination chemistry.80 Investigations into the chemistry of group 15-based coordination complexes of late first-row transition metals, lanthanides, and heavy main group metals have been fruitful.

How many isomers of bipyridine are there?

Bipyridines are of significance in pesticides. Six isomers of bipyridine exist, but two are prominent: 2,2′-bipyridine is a popular ligand. 4,4′-Bipyridine is a precursor to the commercial herbicide paraquat. The bipyridines are all colourless solids, which are soluble in organic solvents and slightly soluble in water.

Are bipyridines soluble in water?

The bipyridines are all colourless solids, which are soluble in organic solvents and slightly soluble in water. 2,2′-Bipyridine (2,2′-bipy) is a chelating ligand that forms complexes with most transition metal ions that are of broad academic interest.

What is the pH of CO2 bipyridine hydroxo complex?

Copper–bipyridine–hydroxo complexes rapidly form in situ from simple commercially available copper salts and bipyridine at high pH. Cyclic voltammetry of these solutions at pH 11.8–13.3 shows large, irreversible currents, indicative of catalysis.
