a. Linear${\mathbf{Ag}}^{\mathbf{+}}$complex ions having CN ligands

b. Tetrahedral ${\mathbf{Cu}}^{\mathbf{+}}$complex ions having ${\mathbf{H}}_{\mathbf{2}}\mathbf{O}$ligands

c. Tetrahedral ${\mathbf{Mn}}^{\mathbf{2}\mathbf{+}}$complex ions having oxalate ligands

d. Square planar${\mathbf{Pt}}^{\mathbf{2}\mathbf{+}}$complex ions having${\mathbf{NH}}_{\mathbf{3}}$ligands

e. Octahedral${\mathbf{Fe}}^{\mathbf{3}\mathbf{+}}$complex ions having EDTA ligands

f. Octahedral${\mathbf{Co}}^{\mathbf{2}\mathbf{+}}$complex ions havinglocalid="1663764385596" ${\mathbf{Cl}}^{\mathbf{-}}$ligands

g. Octahedral ${\mathbf{Cr}}^{\mathbf{3}\mathbf{+}}$complex ions having ethylenediamine ligands
