Question

$\left[Fe{N}_3\right(O_2\left)\right(SCN{)}_4{]}^{4-}$ is named as:

• A. Azidosuperoxidotetrathiocyano - S - ferrate(II)ion
• B. Azidodioxygentetrathiocyanato - S - ferrate(III)ion
• C. Azidoperoxotetrathiocyanato - S - ferrate(II)ion
• D. Azidodioxidotetrathiocyanato - S - ferrate(III)ion

Answer 1

The correct option is A Azidosuperoxidotetrathiocyano - S - ferrate(II)ion

$\left[Fe{N}_3\right(O_2\left)\right(SCN{)}_4{]}^{4-}$

$N_3^{-}$ azido ligand
$O_2^{-}$ Superoxido ligand
$SC{N}^{-}$ Thiocynato ligand

So the name of the complex is Azidosuperoxidotetrathiocyano - S - ferrate(II)
