Coordination compounds serve as catalysts in industrial processes due to their ability to undergo reversible reactions and provide a pathway with lower activation energy. In the hydrogenation of alkenes, a complex like Wilkinson’s catalyst (chlorotris(triphenylphosphine)rhodium(I)) is employed. This rhodium complex facilitates the addition of hydrogen to alkenes, converting them into alkanes. The metal center coordinates with the reactants, promoting the reaction and enhancing selectivity. Coordination compounds as catalysts offer efficiency, regioselectivity, and mild reaction conditions, making them valuable in industrial processes for the production of various chemicals and pharmaceuticals.

[Ag(CN)₂]⁻ and [Au(CN)₂]⁻ complexes are crucial in electroplating due to their stability and ability to provide metal cations for reduction. In silver electroplating, [Ag(CN)₂]⁻ is reduced to deposit a thin layer of silver on a substrate. Similarly, [Au(CN)₂]⁻ is used for gold electroplating. In black and white photography, coordination compounds play a role in fixing the image. After exposing a photosensitive film to light, unexposed silver halide grains are removed. The remaining silver halides are reduced to elemental silver by a developing agent, forming the black areas of the image. Coordination compounds like sodium thiosulfate then fix the image by solubilizing unexposed silver halides, preventing further development.

Chelation therapy is applied in medicinal chemistry to treat metal intoxication by using chelating agents that form stable complexes with toxic metal ions, aiding their removal from the body. For excess copper removal, penicillamine is used. Deferoxamine is a chelating ligand for iron overload therapy, forming a stable complex with iron. Ethylenediaminetetraacetic acid (EDTA) is employed to chelate lead ions. These ligands coordinate to the metal ions, enhancing their excretion through urine or feces. Chelation therapy helps mitigate metal toxicity by facilitating the elimination of excessive metal ions from the body and preventing further damage.
In Valence Bond Theory (VBT) and Crystal Field Theory (CFT), metal atoms or ions in coordination compounds form hybridized orbitals through a process called hybridization.

In Valence Bond Theory (VBT) and Crystal Field Theory (CFT), metal atoms or ions in coordination compounds form hybridized orbitals through a process called hybridization. In VBT, the metal atom/ion undergoes hybridization of its valence orbitals (ns, np, nd) to yield a set of equivalent orbitals with defined geometry (e.g., octahedral, tetrahedral). CFT, on the other hand, focuses on the electrostatic interactions between metal ions and ligands, leading to the splitting of d orbitals. These hybridized orbitals, derived from metal valence orbitals or modified d orbitals, overlap with ligand orbitals, facilitating the formation of coordination bonds in specific geometries.

Several alternative theories have been proposed to explain the bonding in coordination compounds, offering diverse perspectives. Valence Bond Theory (VBT) emphasizes the overlap of metal and ligand orbitals. Crystal Field Theory (CFT) focuses on electrostatic interactions and the splitting of metal d orbitals. Ligand Field Theory (LFT) considers the effects of ligands on metal d orbitals, incorporating covalent and ionic aspects. Molecular Orbital Theory (MOT) involves the formation of molecular orbitals through the combination of metal and ligand atomic orbitals.
