CHXII09:COORDINATION COMPOUNDS

322346 A coordination compound of cobalt has molecular formula containing five ammonia molecules, one nitro group and two chlorine atoms for one cobalt atom. One mole of this compound produces three mole ions in an aqueous solution. On reacting this solution, with excess of \(\mathrm{AgNO}_{3}\) solution two moles of \(\mathrm{AgCl}\) get precipitated. The ionic formula of this complex would be

1 \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{NO}_{2} \mathrm{Cl}\right]\left[\left(\mathrm{NH}_{3} \mathrm{Cl}\right]\right.\)
