A coordination compound has the formula CoCl3.4NH3. It does not liberate ammonia but forms a precipitate with AgNO3. Write the structure and IUPAC name of the complex compound.
The oxidation state of Co in this complex is +3 and that its coordination number is 6. Since, it does not liberate ammonia, the 4 NH3 groups are coordinated to Co. In order to satisfy the coordination number of Co, two chlorides are also coordinated. Therefore, the formula of the complex compounds is [Co(NH3)Cl2]Cl and its IUPAC name is 4 tetraamminodichlorocobalt(III) chloride.
