What is the coordination number in the complex Fe bipy 3 2+?
8), which gave a conclusion that bipyridine is coordinated as a bidentate ligand and the iron(II) has a coordination number of 6.
What is bipy in chemistry?
2,2′-Bipyridine (bipy or bpy, pronounced /ˈbɪpiː/) 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 strong field ligand?
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. Complexes with main group metal ions, and with lanthanides and actinides, can be prepared in water or organic solvents.
Is bipy planar?
The answer to the question in the title is that bipyridine is seldom planar in metal complexes and that the deviation from planarity can be described in terms of bow and twist deformations and to a lesser extent in terms of an S-shaped distortion. There is also an in-plane deformation, which is far from negligible.
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.
How many electrons does BIPY donate?
4 4

What is BIPY used for?
Its complexes are used in studies of electron and energy transfer, supramolecular and materials chemistry, and catalysis. 2,2′-Bipyridine is used in the manufacture of diquat.
Is BIPY a pi-acceptor?
A simple explanation to that question is that bipyridine is conjugated in a dissonant fashion. Charge donation into such systems results in stabilization, therefore bipyridine is found among the pi-acceptor ligands.
Is pyridine a chelate?
In result, and owing to their unique properties as bases, rather high electron density, high positive heat of formation, and good thermal stability [4, 5, 6, 7] pyridines and related derivatives are efficiently utilized as chelates ( stabilizing agents ) for the different electron-deficient metal ions in coordination …
What is BIPY soluble in?
The bipyridines are all colourless solids, which are soluble in organic solvents and slightly soluble in water.
What can you do with a complex number?
From a purely mathematical standpoint, one cool thing that complex numbers allow us to do is to solve any polynomial equation. For example, the polynomial equation does not have any real solutions nor any imaginary solutions.
Can a complex number have both real and imaginary parts?
Either Part Can Be Zero. So, a Complex Number has a real part and an imaginary part. But either part can be 0, so all Real Numbers and Imaginary Numbers are also Complex Numbers.
When to use 7i or −7i in complex numbers?
We use 7i and not −7i because the principal root of 49 is the positive root. A complex number is the sum of a real number and an imaginary number. A complex number is expressed in standard form when written a + bi where a is the real part and b is the imaginary part. For example, 5 + 2i is a complex number.
How are complex numbers expressed in standard form?
A complex number is expressed in standard form when written a + bi where a is the real part and b is the imaginary part. For example, 5 + 2i is a complex number. So, too, is 3 + 4i√3. Imaginary numbers differ from real numbers in that a squared imaginary number produces a negative real number.
