Identify the coordination isomer of [Fe(CO)4][Zn(CN)4].(a) Tetracyanid

1.	Identify the coordination isomer of [Fe(CO)4][Zn(CN)4].(a) Tetracyanidozinc(II) tetracarbonylferrate(II)(b) Tetracarbonylzinc(II) tetracyanidoferrate(II)(c) Tetracyanidoiron(II) tetracarbonylzincate(II)(d) Tetracarbonyliron(II) tetracyanidozincate(II)The question was asked in an interview for job.I want to ask this question from Isomerism in Coordination Compounds in section Coordination Compounds of Chemistry – Class 12
Answer» Correct option is (b) Tetracarbonylzinc(II) tetracyanidoferrate(II) Explanation: The coordination ISOMER will be [Zn(CO)4][Fe(CN)4] by interchanging the central atoms between the TWO complexes with [Zn(CO)4]^2+ being the cationic complex and [Fe(CN)4]^2- being anionic. The naming will be tetracarbonylzinc(II) tetracyanidoferrate(II).
