Coordination Compound

Uses of coordination compounds (a) Dyes and Pigments Coordination compounds have been used from the earliest times as dyes and pigments, for example madder dye…

Haemoglobin in the red blood cells carries oxygen from the lungs to the tissues. It delivers the oxygen molecule to myoglobin in the tissues. When…

Chlorophyll is a magnesium – porphyrin complex. The magnesium is at the centre of the modified porphyrin ring septeon (corrin). The oxidation state of magnesium…

Nature of haemoglobin and myoglobin Both are having the same structure excepting the fact that myoglobin is a monomer and haemoglobin is a tetramer. Both…

In a bimetallic complex, both complex cation and complex anion may be present. In such a case the distribution of ligands between the two coordination…

Coordination compounds having the same molecular formula but forming different ions in solution are called ionization isomers. This property is known as ionization isomerism. An…

Solvate or hydrate isomerism are the isomers that have similar composition but differ with respect to the number of solvent ligand molecules as well as…

Linkage isomerism occurs with ambidentate ligands. These ligands are capable of coordinating in more than one way. The best-known cases involve the monodentate ligands SCN-/NCS-…

Ligand isomerism arises from the presence of ligands which can adopt different isomeric forms. An example is provided by diamino propane, which may have the…

The coordination number of a metal ion in a complex can be defined as the number of ligand donor atoms to which the metal is…
