Isomerism in Coordination Compounds

Just as organic compounds show isomerism, coordination compounds with the very same molecular formula can differ in how their ligands are arranged around the central metal atom, giving rise to compounds with different physical and chemical properties. The chapter organises the common types into two families: structural (constitutional) isomerism, which arises from differences in how the atoms are actually connected, and stereoisomerism, whic …

Figure 5.2Overview of isomerism in coordination compounds

What this figure shows. A branching flow chart headed 'Isomerism', splitting first into two families: 'Structural Isomerism' (arising due to differences in the structures/connectivity of the coordination compounds), which further branches into Ionisation isomerism, Hydration isomerism, Linkage isomerism and Coordination isomerism; and 'Stereo Isomerism' (arising due to different spatial orientation of ligands around the metal ion), which further branches into Geometrical isomerism and Optical isomerism. This chart is the …
