The complex ${\mathrm{K}}_3[\mathrm{Co}({\mathrm{C}}_2{\mathrm{O}}_4{)}_2{\mathrm{Cl}}_2]$ is of the type $[{\mathrm{Ma}}_2{\mathrm{b}}_2{\mathrm{c}}_2]$ where 'a' and 'b' are bidentate ligands and 'c' is a monodentate ligand. This complex can exist as cis- and trans- isomers. The cis- isomer is optically active, existing as a pair of enantiomers (d- and l-forms). The trans- isomer is optically inactive (meso compound). Thus, there are three stereoisomers in total: cis-d, cis-l, and trans.
