Question

Quizplus · Accepted Answer

The complex has a cobalt(III) ion coordinated with six ammonia molecules and two bidentate ligands formed by thiolate (-S-) and isocyanide (-CN) groups, commonly abbreviated as [Co(NH3)6(S2CNR)2]3+. The isocyanide ligand is designated as S1U1B0 in the name. The oxidation state of chromium is +3 and it is coordinated with two cyanide ligands, forming [Cr(CN)2]3-. Therefore, the correct name is hexamminecobalt(III) hexacyanochromate (III).
