In complex compounds,ligands act as:

The primary valency and secondary valency of the central metal ion and the number of total ions produced in an aqueous solution for the $K[Co(OX)_2(NH_3)_2]$ complex are,respectively, . . . . . . .

The bonds present in $K_4[Fe(CN)_6]$ are ........

The number of precipitable halide ions in the sample $[Pt(NH_3)Cl_2Br]Cl$ will be

One mole of the coordination compound $Co(NH_3)_5Cl_3$ gives $3$ moles of ions upon dissolution in water. Furthermore,one mole of this complex reacts with $2$ moles of $AgNO_3$ solution to produce $2$ moles of $AgCl(s)$. The structure of the complex is:

The correct charge and coordination number of $Fe$ in $K_3[Fe(CN)_6]$ is
