The hybridisation of [ Co F6] 3– and [ Co (C2O4)3 ]3 – are :
A
Both sp3d2
B
Both d2sp3
C
sp3d2 and d2sp3 respectively
D
d2sp3 and sp3d2 respectively
Answer
sp3d2 and d2sp3 respectively
Explanation
Solution
In both complexes the oxidation state of cobalt is +3 with 3d6 configuration. Except [CoF6]3–, all other complexes of cobalt with weak field and strong field ligands are inner orbital complexes and diamagnetic because of higher CFSE.
