Question
Out of [CoF6]3- and [Co(en)3]3+, which one complex is
(i) paramagnetic
(ii) more stable
(iii) inner orbital complex and
(iv) high spin complex
(Atomic no. of Co = 27)

Solution
Co (Z=27)=1s2 2s2 2p6 3s2 3p6 4s2 3d7
Co+3 =1s2 2s2 2p6 3s2 3p6 3d7
F- is weak field ligand:
[CoF6]3-
(i) [CoF6]3- is paramagnetic due to the presence of four unpaired electrons
(ii) [Co(en)3]3+ is more stable due to chelation
(iii) [Co(en)3]3+ forms inner orbital complex (d2sp3)
(iv) [CoF6]3+ Forms high spin complex (sp3d2)
