1. $[NiC{l}_2(PP{h}_3{)}_2]$

4-coordinate Ni²⁺

With bulky PPh₃, this is typically tetrahedral, not square planar

No geometrical isomerism

2. $[Co(en{)}_3{]}^{3+}$

Only optical isomerism

No GI

3. $[FeC{l}_2(C_2{O}_4{)}_2{]}^{3-}$

Octahedral with bidentate ligands

Geometrical isomerism possible

4. $[Co{F}_3(H_{2}O{)}_3]$

Type MA₃B₃

fac/mer isomerism

5. $[CoB{r}_{2}C{l}_2{]}^{2-}$

Tetrahedral

No GI

6. $[PtC{l}_2(N{H}_3{)}_2]$

Square planar

cis/trans isomerism
