predict the geometries of the complexes from these reactions:
1- [pt(NO2)cl3)]2- + NH3 --> [pt(NO2)(NH3)cl2]-1 +cl-
2-cis-[pt(RNH2)2(NH3)(NO2)]+1 + cl- --> Pt(RNH2)(NH3)(NO2)Cl + RNH2
1- [pt(NO2)cl3)]2- + NH3 --> [pt(NO2)(NH3)cl2]-1 +cl-
2-cis-[pt(RNH2)2(NH3)(NO2)]+1 + cl- --> Pt(RNH2)(NH3)(NO2)Cl + RNH2
