-
Solid state substitution reactions take place between (Co(NH3)4CO3)Cl or (Co(en)2CO3)Cl with NH4SCN at 100℃, with the non-volatized CO32- being substituted outside the inner coordination sphcrc by SCN-. Trans-(Co(NH3)4(NCS)2)Cl is formed in the reaction of (Co(NH3)4CO3)Cl with NH4SCN. However, in the reaction bctwccn(Co(en)2CO3)Cl and NH4SCN, Cis-Co(en)2(NCS)2Cl is at first formed transforming into trans-isomer ultimately. Two reactions are believed to proceed through SN2 mechanism.
