Why is geometrical isomerism not possibl...

Why is geometrical isomerism not possible in tetrahedral complexes having two different types of unidentate ligands Co-ordinated with the central metal ion ?

Text Solution

Verified by Experts

Tetrahedral complexes do not show geometrical isomerism because the relative positions of the unidentate ligands attached to the central metal atom are the same with respect to each other.

Complex compounds can exhibit isomerism like structural and stereo. The complexes containing coordination No. 1, 2, 3 cannot exhibit geometrical isomerism. Geometrical and optical isomerism is common in the complex having coordination number 4 and 6 Ma,b, shows facial and meridonial isomerism. [Co(NH_(3))_(5)(NO_(2))]Cl_(2)and[Co(NH_(3))_(5)ONO]Cl_(2) are

Complex compounds are molecular compounds which retain their indentities even when dissolved in water. They do not give all the simple ions in solution but instead furnish complex ions. The complex compounds are often called coordination compounds because certain groups called ligands are attached to the central metal ion by coordinate or dative bonds. Coordination compounds exhibit isomerism, both structural and stereoisomerism. The struculre, magnetic property, colour and electrical properties of complexes are explained by various theories. which of the following pairs, both the complexes have the same geometry?

A spinel is an important class of oxides consising of two types of metal ions with the oxide ions arranged in cop layers. The normal spinel has one-eigth of the tetrahedral holes occupied by one type of metal ion and one-half of the octahedral holes occupied by another type of metal ion. Such a spinel is formed by Mg^(2+), A^(2+) and O^(2-) . The neutratrality of the crystal is maintained. Type of hole occupied by Al^(3+) ions is :
