The splitting diagram for square planar ...

The splitting diagram for square planar complexes is more complex than for octahedral and tetrahedral complexes and is shown below with the relative energies of each orbital.

Calculate crystal field stabilisation energy for a diamagnetic square planar `d^(8)` metal complex with the help of above diagram neglecting pairing energy (P)

A

`-2.88Delta_(0)`

B

`-2.44Delta_(0)`

C

`-1.65Delta_(0)`

D

`-4.84Delta_(0)`

Text Solution

Verified by Experts

The correct Answer is:
B
`d_(xz)^(2),d_(yz)^(2),d_(z^(2))^(2),d_(xy)^(2) =d^(8)`
CFSE`=4xx(-0.51Delta_(0))+2xx(-0.4Delta_(0))+2xx(0.23Delta_(0))`
`=-2.44Delta_(0)`
