What is the charge of phen?

What is the charge of phen?

phenanthroline (phen) Phenanthroline is a neutral molecule containing two N atoms that can each donate a pair of electrons to a metal atom.

What is O phen ligand?

Abbreviated “phen”, it is used as a ligand in coordination chemistry, forming strong complexes with most metal ions. It is often sold as the monohydrate.

What is the chemical formula of 1/10-phenanthroline?

Property Name Property Value Reference
Topological Polar Surface Area 25.8 Ų Computed by Cactvs (PubChem release 2021.10.14)

Is phen a pi acceptor ligand?

Moreover, the presence of low-lying LUMO orbitals and the consequent high electron affinity enables Phen to show enhanced π back acceptance characteristics as compared to the other two ligands.

What does phen mean in chemistry?

Phen, an abbreviation for the chemical compound phenethylamine.

Is BIPY a neutral ligand?

The bipyridine ligand has been widely used as metal chelating ligand due to its robust redox stability and ease of functionalization. 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 type of ligand is phenanthroline?

chelating bidentate ligand
1,10-Phenanthroline (phen) is a classic chelating bidentate ligand for transition metal ions that has played an important role in the development of coordination chemistry [1], [2], [3] and still continues to be of considerable interest as versatile starting material for organic, inorganic and supramolecular chemistry.

What is phenanthroline method?

Summary. A rapid, accurate method for the determination of iron using hydroxylamine hydrochloride, sodium acetate buffer, and 1,10-phenanthroline is described. The ash is taken up with hydrochloric acid (1 + 1) and heated for 5 minutes. No interference from pyrophosphates, copper and nickel was observed.

Is Bipyridine chelating ligand?

2,2′-Bipyridine is the most widely used chelating ligand for forming metal complexes in coordination and supramolecular chemistry.

What is a pi donor ligand?

Pi-donor ligands In coordination chemistry, a pi-donor ligand is a kind of ligand endowed with filled non-bonding orbitals that overlap with metal-based orbitals. Their interaction is complementary to the behavior of pi-acceptor ligands.

Is Phen a prefix?

1. a combining form meaning “shining,” “appearing, seeming”: phenocryst. 2. a combining form used in the names of chemical compounds that contain phenol or the phenyl group, are related to aromatic compounds, or derive from benzene: phenobarbital.

What type of ligand is bipy?

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 bipy a pi acceptor?

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

Which type of ligand is 1/10-phenanthroline?

How do you make phenanthroline?

Prepare a 1,10-phenanthroline solution by dissolving 0.1 g of 1,10-phenanthroline in 30 mL of distilled water with the aid of stirring and gentle heating. Cool and dilute to 50 mL. Store in a dark place. Preparation of Standard Iron Solutions and Calibration Curve.

Does bipyridine have a charge?

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 charged?

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 sigma and pi donor?

This situation is called “back-bonding” because the ligand donates σ-electron density to the metal and the metal donates π-electron density to the ligand. The ligand is thus acting as a σ-donor and a π-acceptor.
