The IUPAC name of the given compound is Pentaamminechloridocobalt(III) chloride.

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

The electronic configuration is d6.

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{0(0+2)}\ =\ 0BM
