Low spin complexes are coordination complexes containing paired electrons at low energy levels . Since there are no unpaired electrons in the low spin complexes (all the electrons are paired), they are diamagnetic. This means these compounds cannot be attracted to an external magnetic field.
What is low spin complex example?
The usual Hund’s rule and Aufbau Principle apply. Examples of low-spin d6 complexes are [Cr(CN)6]3− and Cr(CO)6 , and examples of high-spin d6 complexes are [CrCl6]3− and Cr(H2O)6 .
Which of the following is low spin complex?
Low spin complexes are coordination complexes containing paired electrons at low energy levels . Since there are no unpaired electrons in the low spin complexes (all the electrons are paired), they are diamagnetic. This means these compounds cannot be attracted to an external magnetic field.
Which of the following is low spin spin paired complex?
Fe3+=[Ar]3d54s0; the ferric ion has d2sp3 hybridisation and forms inner orbital or low spin complex having one unpaired electron.
Is CoF6 low spin complex?
[Co(C 2 O 4 ) 3 ] 3 – As the oxalate have -2 charge and is a strong field ligand, it allows to pair electron of Co in its exited state hence there is pairing of electrons which makes it more stable, so it is diamagnetic, low spin complex , inner orbital complex with d 2 sp 3 hybridisation.
How do you get a low spin complex?
Another method to determine the spin of a complex is to look at its field strength and the wavelength of color it absorbs . If the field is strong, it will have few unpaired electrons and thus low spin. If the field is weak, it will have more unpaired electrons and thus high spin.
Why are there no low spin tetrahedral complexes?
Answer: In tetrahedral complex, the d-orbital is splitting to small as compared to octahedral. ... Hence, the orbital splitting energies are not enough to force pairing . As a result, low spin configurations are rarely observed in tetrahedral complexes.
Which of the following is the example of d6 low spin complex?
Examples of low-spin d6 complexes are [Cr(CN)6]3− and Cr(CO)6 , and examples of high-spin d6 complexes are [CrCl6]3− and Cr(H2O)6.
Is Fe3+ high or low spin?
In post-perovskite, the octahedral-site Fe3+ remains in the low-spin state at the pressure conditions of the lowermost mantle.
Which of the following complex is high spin?
The Questions and Answers of Which of the following complex is high spin? a)K4[Fe(CN)6]b)[PtCl4]2c)[CoF6] 3d)[Ni(NH3]6 ]2+Correct answer is option ‘C’.
Which among the following is high spin and outer orbital complex?
(d) [Co(NH3)6]3+ and [Ni(CN)4]2- are inner d-orbital or low spin complex and [NiCI4]2- complex has sp3 -hybridisation and has tetrahedral geometry while [CoF6]3- is outer d-orbital or high spin complex .
Which ligand among the following produces low spin complexes?
NO-2 is able to cause the pairing of electrons so low spin complex will form.
What are EG and t2g orbitals?
The five d orbitals in an isolated gaseous metal atom/ion have same energy, i.e., they are degenerate. ... The dxy, dxz, and dyz orbitals are collectively called the t2g orbitals, whereas the dz2 and dx2-y2 orbitals are called the eg orbitals.
Can low spin complexes be paramagnetic?
(c) Low spin complexes can be paramagnetic .
Why is CoF6 high spin?
Fluorine ion is a weak ligand. It cannot cause the pairing of the 3d electrons. As a result, the Co 3 + ion will undergo sp 3 d 2 hybridzation. The complex formation involves d-orbitals of the outershell which give a high spin complex.
Is H2O 6 3+ high spin or low spin?
Most aquo complexes are high spin , because H2O is a weak- field ligand. [Co(H2O)6]3+, except [CoF6]3–, which is high spin.
