30 Questions around this concept.
A solution contains 2.675 g of $\mathrm{CoCl}_3 \cdot 6 \mathrm{NH}_3$ (molar mass = 267.5 g mol-1) is passed through a cation exchanger. The chloride ions obtained in solution were treated with excess of AgNO3 to give 4.78 g of AgCl (molar mass = 143.5 g mol-1) . The formula of the complex is (At. mass of Ag = 108 u)
One mole of the complex compound gives 3 moles of ions on dissolution in water. One mole of the same complex reacts with two moles of
solution to yield two moles of
The structure of the complex is

Which has maximum conductance in water?
The main postulates are:
He further postulated that octahedral, tetrahedral and square planar geometrical shapes are more common in coordination compounds of transition metals. Thus, [Co(NH3)6]3+, [CoCl(NH3)5]2+ and [CoCl2(NH3)4]+ are octahedral entities, while [Ni(CO)4] and [PtCl4]2– are tetrahedral and square planar, respectively.
