SUMMARY
The correct name for the complex CrCl2(en)2 is bis(ethylenediamine) dichlorochromium(II). The oxidation state of chromium in this complex is +2. When naming complexes with two bidentate ligands like ethylenediamine (en), the prefix "bis" is used instead of "di". Additionally, the correct spelling of chromium must be maintained, as "cromide" is incorrect due to the -ide suffix indicating an anion, not a cation.
