Formula of the Complexes:

Potassium trans-dibromo bis (oxalato) Cobaltate (III):
  • Formula: K[Co(C2O4)Br2]



Sodium bis (thiosulphato) aurate (1):
  • Formula: Na[Au(S2O3)2]



Explanation:

Potassium trans-dibromo bis (oxalato) Cobaltate (III)
  • This complex has a cobalt ion in the +3 oxidation state.
  • The ligands present in this complex are oxalate (C2O4) and bromide (Br).
  • The coordination number of the cobalt ion is 6, with two bromide ions and two oxalate ions bonded to it.
  • The complex is named as trans-dibromo bis(oxalato) to indicate the arrangement of ligands around the central cobalt ion.



Sodium bis (thiosulphato) aurate (1)
  • This complex has a gold ion in the +1 oxidation state.
  • The ligands present in this complex are thiosulfate (S2O3) and sodium (Na).
  • The coordination number of the gold ion is 4, with two thiosulfate ions bonded to it.
  • The complex is named as bis(thiosulphato) to indicate the presence of two thiosulfate ligands.
