As coordination no. is 6, so according to CFT d orbitals will split in 2 groups of t2g (dxy+dyz+dzx) and eg(dx²-y²+dz²), with energy of t2g lower.As (CN)¹- is a strong ligand therefore pairing of electrons will take place. Fe²+ has d6 configuration.All the 6 electrons will get filled up in the 3 orbitals of t2g,so no unpaired electron is left,hence compound is diamagnetic.
