Homework Statement



Name the complex CrCl2(en)2. The oxidation number of chromium is +2

Homework Equations



when there are two (en)s, you use bis instead of di because it is bidentate

The Attempt at a Solution



bis-ethylenediaminedichlorocromide(II)
bisethylenediaminedichlorocromide(II)

I've checked the spelling, etc., a couple of times and I'm not sure what is wrong with it...

bis(something) not bis-something.

Cr is not cromide. Remember that the -ide suffix is used to denote an anion, not a cation. In this example, chromium is in the +2 oxidation state, a cation.
