How many geometrical isomers are possible for each of the following complexes? Draw the structure of each isomer:
$$[Cr(en)_2Br_2]^+$$
Metal complexes that differ only in which ligands are adjacent to one another (cis) or directly across from one another (trans)
in the coordination sphere of the metal are called $$Geometrical\space isomers$$.
Therefore, $$[Cr(en)_2Br_2]^+$$ has $$two$$ Geometrical isomers i.e $$cis-[Cr(en)_2Br_2]^+$$ and $$trans-[Cr(en)_2Br_2]^+$$
