(i) K[Cr(H2O)2(C2O4)2]K[Cr(H_2O)_2(C_2O_4)_2]
(ii) [Co(en)3]Cl3[Co(en)_3]Cl_3
(iii) [Co(NH3)5(NO2)](NO3)2[Co(NH_3)_5(NO_2)](NO_3)_2
(iv) [Pt(NH3)(H2O)Cl2][Pt(NH_3)(H_2O)Cl_2]
Solution:  
(i) Both geometrical (cis-, trans-) and optical isomers (for cis) canexist.
(ii) Two optical isomers can exist.(ii) Two optical isomers can exist.
(iii) Ionization isomers :
[Co(NH3)5(NO2)](NO3)2,[Co(NH3)5(NO3)](NO2)(NO3)[Co(NH_3)_5 (NO_2)] (NO_3)_2, [Co(NH_3)_5 (NO_3)](NO_2)(NO_3)
Linkage isomers : [Co(NH3)5(NO2)](NO3)2,[Co(NH3)5(ONO)](NO3)2[Co(NH_3)_5(NO_2)](NO_3)_2 , [Co(NH_3)_5 (ONO)](NO_3)_2
(iv) Geometrical (cis-, trans-) isomers can exist.
