Question

Write down the IUPAC name of the following complex and indicate the oxidation state, electronic configuration and coordination number. Also, give the stereochemistry and magnetic moment of the complex:

Cs[FeCl₄]

Answer 1

IUPAC name of the hybrid compound	Oxidation state of the central metal	Coordination number	Shape	Central metal ion	Electronic configuration	The value of n and the magnetic moment	Stereochemistry
Caesium tetrachloridoferrate(III)	+1 + x + 4 × (−1) = 0 ∴ x = +3	4	Tetrahedral	Fe3+	3d5, \[\ce{t^3_{2g}e^2_g}\]	n = 5, `sqrt(5(5 + 2))` = 5.92 BM	Optically inactive
