Which of the following compounds does not have a coordination isomer?(

1.	Which of the following compounds does not have a coordination isomer?(a) [Ag(NH3)2][Ag(CN)2](b) [Cr(NH3)6][Co(CN)6](c) [Zn(NH3)4][PtCl4](d) [Cu(NH3)4][FeCl4]The question was asked in homework.This interesting question is from Isomerism in Coordination Compounds in portion Coordination Compounds of Chemistry – Class 12
Answer» The correct choice is (a) [Ag(NH3)2][Ag(CN)2] Best explanation: Coordination isomerism takes PLACE when exchange of ligands happens between cationic and ANIONIC complex IONS having different metal ions. In the COMPOUND [Ag(NH3)2][Ag(CN)2], both the complexes have the same metal ion Ag^+, and hence does not have a coordination isomer.
