Writh the structure and name og the following and their coordination isomers .

Explanation

The coordination isomer of `(A)` is `[Cr (en)_(3)][Co(CN)_(6)]` The structure name of the above two isomers are given below `(A)`implies Tris (ethylenediamine)coblt(III) hexacyanochromate (III) and its isomer Tris (ehtylenediamine)chromium (III) hexacyanocobaltate (III)
(ii) Coordination isomer of `(B)` is `[Cr(NH_(3))_(6)][Co(C_(2)O_(4))_(3)]` The structure and name of these isomers are given below (B)implies Hexamminecobalt (III) tris (oxalato) chromate (III) and its isomer
`[Cr(NH_(3))_(6)][Co(C_(2)O_(4))_(3)]` is
Hexamminechromium (III) tris (oxalato)cobaltate(III) .
