Other than the X-ray diffractions, how could be the following pairs of isomers be distinguished from one another by ;
[Cr(NH 3 ) 6 ] [Cr(NO 2 ) 6 ] and [Cr(NH 3 ) 4 (NO 2 ) 2 ] [Cr(NH 3 ) 2 (NO 2 ) 4 ]

[Cr(NH 3 ) 6 ] 3+ [Cr(NO 2 ) 6 ] 3– and [Cr(NH 3 ) 4 (NO 2 ) 2 ] + [Cr(NH 3 ) 2 (NO 2 ) 4 ] – have same number of ions, so cryoscopic method can not be used.
Molar conductance depends on the number of ions as well as on the charge on the complexes. [Cr(NH 3 ) 6 ] 3+ [Cr(NO 2 ) 6 ] 3– and [Cr(NH 3 ) 4 (NO 2 ) 2 ] + [Cr(NH 3 ) 2 (NO 2 ) 4 ] – have same number of ions but different electrical charges.
Both complexes have same number of unpaired electrons, so measuring magnetic moments methods can not be used.
They have similar colour because of the similar conditions.
