The IUPAC name of the given compound is Caesium tetrachloroferrate (III).

The oxidation state of Cs in this compound is +3. 

The electronic configuration is d5.

The coordination number of this compound is 4.

The magnetic moment of a compound is given by : 

                                                                                      =\ \sqrt{n(n+2)}                                  Here n is the number of the unpaired electrons.

 or                                                                                  =\ \sqrt{5(5+2)}\ =\ \sqrt{35}BM=5.92
