How does bis(glycinato) Nickle exhibit optical isomerism?
I'm a medical practitioner but sometimes I find time to discuss few topics of chemistry with my son who has just passed out his 12th standard exams. Regarding optical isomerism I have learned that a ...

Is hydroxylamine monodentate or ambidentate ligand?
What is the total number of geometric isomers of the complex $\ce{[Pt(Cl)(py)(NH3)(NH2OH)]+}$?
If $\ce{NH2OH}$ acts as an ambidentate ligand, then there should be six geometric isomers. Or is it ...

Why total stereoisomers is 1 even if no geometrical isomers and optical-isomers are present [closed]
Let's for example take the complex structure type $\ce{MA_6}$, What will be the Total number of Stereo-isomers (=[Geometrical-isomers]+[optical-isomers]).
My effort was that There will be no G.I and ...

Is a tetrahedral complex with two symmetric bidentate ligands optically active?
If the shape of of a complex $\ce{M(AA)2}$ (with $\ce{AA}$, a bidentate ligand) is tetrahedral, then is it optically active?
Currently I know that it is optically inactive, but I want to know the ...

Why is [M(AB)2] a geometrical isomer?
Our teacher told us that for coordination number 4 and tetrahedral shape $\ce{[M(AB)2]}$ doesn't have a plane of symmetry, so it shows optical isomerism.
What if we take a plane passing through the ...

Why are complexes of type MA3B3 not optical active?
Complexes of type $\ce{MA3B3}$ have two geometrical isomers, namely:
fac-isomer
mer-isomer
If we look closely at the mer-isomer, it has a plane of symmetry, so it is optically inactive.
But the fac-...

Which are the Geometrical isomers of the complex [Cr(NH3)2Cl2(en)]+?Is it one or two?
I was recently studying coordination compounds and i came across optical isomerism shown by complexes.I think that the complex i gave above have 4 geometrical isomers(I think this is where I am wrong, ...

Why does [Ni(gly)2] show optical isomerism despite having no chiral carbon?
For optical isomerism chiral carbon should be present i.e. carbon with four different groups but this compound doesn't have one then why does it show optical isomerism?

Number of optically active isomers of [Co(NH3)2Cl2(NO)(OH)]?
My Attempt:
Since Compound is of the form M[a2b2cd]
I got three optically active isomers of the form M[(ab)(ab)(cd)] , M[(ab)(ac)(bd)] , M[(ab)(bc)(ad)]
and since NO is a bidentate ligand, total ...

Will the following complex show optical isomerism
So there is this question which asks whether the following complex
$\ce{[Co(NH3)4Br2]+}$
will show optical isomerism or not.
According to my knowledge it will show optical isomerism in cis ...

Optical activity of cis coordination compounds
I came across a statement saying,
"Consider a Octahedral coordination compound of type [MA2X2]. Then,
if the compound is in a cis form, it shows optical activity as there
is no plane of ...

Why does only the cis-isomer of potassium dioxalatodiaquochromate(III) form?
A friend of mine performed a standard synthesis reaction of potassium dioxalatodiaquochromate(III) by adding potassium dichromate to ethandioic acid dihydrate and a little water. The synthesis ...

Why do tetrahedral organic molecules show stereo-isomerism, but not tetrahedral transition metal complexes?
Both types of molecules show different arrangements of the molecule in space, so they should qualify for optical isomerism right?
