How many geometrical isomers are possible in $\left[{\mathrm{Pd}}^{2+}{\left({\mathrm{NH}}_2-\mathrm{CH}\left({\mathrm{CH}}_3\right)-{\mathrm{CO}}_2^{-}\right)}_2\right]?$

Geometrical Isomers in Pd²⁺ Complex with Amino Acid Ligands

The coordination complex Pd²⁺ NH₂–CHCH₃–COO₂^– involves palladium in a square planar geometry, coordinated with two bidentate amino acid ligands.

Such square planar complexes with two bidentate ligands exhibit two geometrical isomers:

• Cis isomer: Both ligands adjacent to each other around Palladium center.
• Trans isomer: Ligands opposite each other around Palladium center.

Therefore, the number of possible geometrical isomers is 2.
