Pls tell ....hybridisation & shape of [Co(NH3)Cl2]Cl......its not [Co(Nh3)4Cl2]Cl

Dear Student,

The Complex [Co(NH₃)Cl₂]Cl does not exist, because Cobalt (Co) only forms complexes with Coordination numbers 4 and 6.
And in this case, the Coordination number is 3, which is not possible with Cobalt. Therefore, the compound is [Co(NH₃)₄Cl₂]Cl.
