chlorido bis (ethelene diamine) nitrito cobalt III

Answer 2

IUPAC name of $Co(en)_2Cl(NO_2)]^+$ is chloro bis(ethylenediamine) nitro cobalt(III)

Explanation:

Rules for naming of the coordination compounds :

a) The ligands are named first then metal.

b) The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.

c) The ligands are named in alphabetical order before the metal ion.

d) that include a numerical prefix in the name use the prefixes bis for 2, tris for 3, or tetrakis for 4 to indicate their number.

e) If the complex ion is an anion, we drop the ending of the metal name and add –ate.

In the given coordination compound $Co((en)_2Cl(NO_2)]^+$, Co is the cobalt metal,  en , Cl and $NO_2$ are the named as ethylenediammine, chloro and nitro.

The charge on , is +1. en is neutral, chloro is having an oxidation state of -1 and nitro is having an oxidation state of -1.

x+2(0)+1(-1)+1(-1)=+1

x=+3

Hence, the IUPAC name of $Co((en)_2Cl(NO_2)]^+$ is chloro bis(ethylenediamine) nitro cobalt (III)
