The manganate and permanganate ions are tetrahedral, due to:

1. The $\mathrm{\pi }$ -bonding involves overlap of $\mathrm{p}$ -orbitals of oxygen with $\mathrm{d}$ -orbitals of manganese
2. There is no $\mathrm{\pi }$ -bonding
3. The $\mathrm{\pi }$ -bonding involves overlap of $\mathrm{p}$ -orbitals of oxygen with $\mathrm{p}$ -orbitals of manganese
4. The $\mathrm{\pi }$ -bonding involves overlap of $\mathrm{d}$ -orbitals of oxygen with $\mathrm{d}$ -orbitals of manganese

Solution

The manganate and permanganate ions are tetrahedral due to the $\mathrm{\pi }-$ bonding involves overlap of $\mathrm{p}-$ orbitals of oxygen with $\mathrm{d}-$ orbitals of manganate.
