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.

PREREQUISITES
  • Understanding of coordination chemistry and complex nomenclature
  • Familiarity with bidentate ligands, specifically ethylenediamine (en)
  • Knowledge of oxidation states and their implications in naming
  • Basic grasp of chemical suffixes and prefixes in nomenclature
NEXT STEPS
  • Study the IUPAC nomenclature rules for coordination compounds
  • Learn about the properties and applications of bidentate ligands
  • Explore examples of naming other coordination complexes with varying oxidation states
  • Investigate the role of ligands in determining the geometry of coordination complexes
USEFUL FOR

Chemistry students, educators, and professionals involved in coordination chemistry and complex nomenclature.

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.
