WebThe Given complex [Pt(en) 2Cl 2] The primary valence is its oxidation number i.e +2 and the secendory valency is its coordination number i.e 6 in this case. (The en ligand is bidentate, and Cl is monodentate).The second possibility is that compound can exist as [Pt(en) 2]Cl 2 and hence the primary valency can also be +2 and secondary valence is 4. WebThese are satisfied by negative ions. Also, the secondary valence is fixed for any metal and is equal to its coordination number. The ions bounded by the secondary linkages to the metal exhibit characteristic spatial arrangements corresponding to different coordination numbers. Difference between Primary and Secondary Valency in Coordination ... WebMar 10, 2024 · -Now we have already seen that the oxidation state of Cr atom is (+3), so the primary valency will be = (+3).-Also 2 bidentate ligands (oxalate) and 2 monodentate ligands (chlorine) are attached to Cr atom, coordination number of Cr will be = 2(2) + 2(1) = 6 Hence the secondary valency will be = 6.
