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?

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 , ,  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.
