Step 1. Enantiomorphs (enantiomers) are non-superimposable mirror images -- only genuinely chiral complexes can form such a pair.

Step 2. [Cr(NH₃)₆][Co(CN)₆]: both ions are simple homoleptic octahedral complexes with no chelate rings -- achiral, no enantiomers; this pair instead illustrates coordination isomerism (Section 5.5.1.2), not optical isomerism.

Step 3. [Co(en)₂Cl₂]Cl: as established for [CoCl₂(en)₂]⁺ (Section 5.5.3), the CIS form of this [M(xx)₂B₂]-type complex is chiral and exists as a genuine pair of non-superimposable mirror-image enantiomers. …
