In [ F e ( C N ) 6 ] 4 - F e is in + 2 state with elctronic configuration 4 s o 3 d 6 and C N - is strong ligand causes inward pairing, thus shows d 2 s p 3 , Octahedral. N i ( C O ) 4 is s p 3 tetrahedral and [ N i ( C N ) 4 ] 2 - is d s p 2 , square planar.

	Geometry: $A$		Complex: $B$
$I$	Octahedral	$(P)$	$[N i (C N)_{4}]^{2 -}$
$I I$	Square planar	$(Q)$	$N i (C O)_{4}$
$I I I$	Tetrahedral	$(R)$	$[F e (C N)_{6}]^{4 -}$
