When a coordination compound PdCl_2.4NH3 is mixed with AgNO₃, 2 moles of AgCl are precipitated per mole of the compound. Write the structural formula of the complex.

The elements present inside the coordination sphere are unable to disassociate and react. 1 mole of Ag need 1 mole of Cl to form AgCl. So, the precipitation of two moles of AgCl governs for two free Cl ions. So the structural formula of complex will be :

[Pd(NH₃)₄]Cl₂
