5 3 Indicate the types of isomerism exhibited by the following complexes and
draw the structures for these isomers:
(i) K[Cr(H2O)2(C2O4)2
(ii) [Co(en)3]Cl3
(iii) [Co(NH3)5(NO2)](NO3)2
(iv) [Pt(NH3)(H2O)Cl2]

It is usually possible to predict the geometry of a complex from
the knowledge of its
magnetic behaviour on
the basis of the valence
bond theory
