How many geometrical isomers are possible in the following coordination entities? (i) [Cr(C2O4)3]3– (ii) [Co(NH3)3Cl3]
(i) In [Cr(C2O4)3]3−, C2O4 is a bidendate ligand. So, no geometrical isomer is possible in this case. (ii) In case of [Co(NH3)3Cl3], two geometrical isomers are possible i.e. facial and meridional.
