Introduction to d-Block ChemistryCoordination Numbers and GeometriesC.N. = 4 cont.:ClPtNNPtClcis-[PtCl (NH ) ]2 3 2trans-[PtCl (NH ) ]2 3 2• Geometrical isomers have different chemical & biologicalproperties. Cisplatin is an anti-cancer drug; trans isomer noteffective as a drug.• NB: Not all d 8 systems are necessarily sq-planar! d 8 Ni(II)can form octahedral, tetrahedral, and square-planarcomplexes.• Forced sq-planar complex also possible:
Introduction to d-Block ChemistryCoordination Numbers and GeometriesC.N. = 4 cont.:• Tetrahedral geometry can be converted into square planar geometry (& viceversa) by ligand displacements (no bonds broken):• Tetrahedral & sq-planar are ideal 4-coordinate geometries. In reality,compounds exist which encompass a range of intermediate (D 2h) ) geometriesas well.
