(i) The structures and IUPAC names of other six complexes are :
(a) `[Pt(NH_3)_(5)Cl]Cl_3` : pentaammine chloridoplatinum (IV) chloride .
(b) `[Pt(NH_3)_(4)Cl_2]Cl_2` : tetraamminechloridoplatinum (IV) chloride .
(c) `[Pt(NH_3)_(5)Cl_3]Cl` : triamminetrichloridoplatinum (IV) chloride
(d) `[Pt(NH_3)CL_4]` : diamminetetrachloridoplatinum (IV) (e) `[Pt(NH_3)Cl_5]^(-)` : amminepentachloridoplatinate(IV)
(f) `[PtCl_6]^(2-)` : hexachloridoplatinare (IV)
(ii) The complex `[Pt(NH_3)_6]Cl_4` has the maximum molar conductivity as it forms maximum ion (five) in solutiion.
(iii) The compound (d) is non-ionic.
(iv) The C.N of Pt in all the complexes is 6.
