Geometrical isomers of complexes may differ in dipole moment and visible / UV spectra

Complexes of the type$\left[{\text{Ma}}_3{\text{b}}_3\right]$can also have facial (fac) and meridional (mer) isomer

No optical isomer exists for the complex trans -${\left[\text{Co}{\left(\text{en}\right)}_2{\text{Cl}}_2\right]}^{+}$

All are correct
