A research guide instructed his two students to synthesize complex
$[C o (N H_{3})_{5} (N O_{2})] C l_{2}$
They synthesized the complexes with identical molecular formula, molar mass, geometry, conductance and spin, but they differed in colour. Bases on the above facts the following question.

(ii) Which of the ligands can show ambient property?
