Co(en)2Br2]cl

Solution ⤵️

Tris(ethylenediamine)cobalt(III) chloride is an inorganic compound with the formula [Co(en)3]Cl3 (where "en" is the abbreviation for ethylenediamine). It is the chloride salt of the coordination complex [Co(en)3]3+. This trication was important in the history of coordination chemistry because of its stability and its stereochemistry. Many different salts have been described. The complex was first described by Alfred Werner who isolated this salt as yellow-gold needle-like crystals.

Answer 2

The iupac name is Dibromidobis(ethylenediammine) Cobalt (III) Chloride.

Rules to find IUPAC name in coordination compounds:

• The atom which is in central should be pace first.
• We have to name the cation before the anion, while naming a coordination compound.
• Ligands are listed alphabetical order.
• We have to use the terms bis, tris, tetrakis if the names of ligands have a numerical prefix.
• We name the central metal atom once naming of the ligand placed in alphabetic order.
• Oxidation state of the metal in cation anion or neutral is indicated by Roman numeral in parentheses.
• We give name to the neutral complex molecule similar to that of the complex cation.
