The IUPAC name of the given compound is Potassium hexacyanomanganate(II).

The oxidation state of Mn in this compound is +2. 

The electronic configuration is d5.

The coordination number of this compound is 6.

The magnetic moment of a compound is given by : 

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

 or                                                                                  \\=\ \sqrt{1(1+2)}\ =\ \sqrt{3}BM\\=1.72BM

Stereochemistry:-    Optically inactive.
