A coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal-containing compounds, especially those of transition metals (d block elements), are coordination complexes.
My attempt-
1)The given ligand forms chelate rings,so it should be a chelating complex.
2)It has no plane of symmetry (P.O.S),so it is optically active(octahedral complex) and should have 2 optically active isomers.
3)They are not polymerisation isomers because they have different emperical...
Ammonia is present in the spectrochemical series near the middle, just after water. Is it a strong field ligand, or a weak field ligand?
Also, take into consideration the complex ##[Ni(NH_3)_4 Cl_2]##. Chloride ion is towards the left end of the spectrochemical series which means it is a weak...

There is something that I am not understanding about the visible colors of coordination complexes. I did a lab where I prepared [Fe(NH2trz)3]Br2 from FeBr2.
Fe(NH2trz)3 was a violet color and FeBr2 was red. My understanding of colors in coordination complexes is that reds are high energy...

Describe, using sketches, how the following ligands can act as both σ-donors and π-acceptors:
CN-
P(CH3)3
SCN-
Homework EquationsThe Attempt at a Solution
I suspect it has something to do with these ligands having lone pair electrons AND open π* orbitals.
How correct is this...

Find spin only magnetic moment of ##[Fe(H2O)5NO]^{2+}##
Homework Equations
None
The Attempt at a Solution
When I used Google, the magnetic moment in 3.87
##Fe## is in +1 oxidation state. So configuration is $$[Ar]3d^64s^1$$
There are 5 unpaired electrons. How does magnetic...
I am confused with the electron configuration of central atoms in complex salts eg. ##[Fe(CN)_6]^{2-}## configuration just Fe atom is
Now the complex is low spin so the configuration becomes,
Now we have 6CN. where will they donate their electrons? Will the donate electrons in the remaining...

Hey,
[Co(NH3)4Cl2]Cl
I don't understand how there isn't just one mole of Cl- ions formed when you dissolve one mole of the compound in water. The answer is '2 moles', but I don't see how :(
Another example is
[Co(NH3)4]Cl3
How many moles of ions are formed when 1 mole of this...
