CHXII09:COORDINATION COMPOUNDS

322029 A coordination complex 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 number of structural isomers shown by the complex is
