Consider the complex ion $[\text{Co}(\text{CN})_6]^{3-}$ and answer the following questions:
(atomic number of $\text{Co} = 27$)
(a)[0.5]
Type of hybridisation of central metal atom
(b)[0.5]
Magnetic nature
(c)[0.5]
Geometry of the complex ion
(d)[0.5]
Low spin complex or high spin complex
Answer
Answer (a)
$d^2sp^3$ (inner orbital complex)
Answer (b)
Diamagnetic (no unpaired electrons, $\mathrm{Co^{3+}}$ is $3d^6$ with all electrons paired)
Answer (c)
Octahedral
Answer (d)
Low spin complex ($\mathrm{CN^-}$ is a strong field ligand and pairs the electrons)
