What is hybridisation and shape ,colour and magnetic behaviour of [Co(NH3)4Cl2]Cl (4marks)

hybridisation : d2sp3
Octahedral shape
low spin, inner orbital complex
occurs as trans isomer (green in colour) and violet cis isomer

Kindly refer to the link for [Co(NH3)6]3+ for hybridisation details:



  • 0

Shape is Octahedral with sp3dhybridised Co atom.

It's diamagnetic due to no unpaired electrons. Use VBT theory to find out.
