Define coordination compounds and give an example?

Coordination compounds are molecules that consist of a central metal atom or ion bonded to ligands. An example of a coordination compound is [Cu(NH3)4(H2O)2]2+. Signup and view all the answers

Explain the concept of coordination number in coordination compounds.

The coordination number refers to the number of donor atoms attached to the central metal ion in a coordination compound. It represents the total number of bonds formed between the metal ion and the ligands. Signup and view all the answers

What is the role of ligands in coordination compounds?

Ligands are molecules or ions that donate a pair of electrons to the central metal ion, forming coordinate covalent bonds. They surround the central metal ion and determine the geometry of the complex. Signup and view all the answers

Study Notes

Coordination Compounds

A coordination number of 6 is exhibited by a complex in which the metal ion is surrounded by six ligands.

Isomerism in Coordination Compounds

Oxidation State of Central Metal Ion

The oxidation state of the central metal ion in the coordination compound [Fe(CN)6]4- is +2.

Definition and Example of Coordination Compounds

Coordination compounds are complexes formed by the coordination of neutral molecules or ions with a central metal atom or ion.
Example: [Fe(CN)6]4- is a coordination compound.

Coordination Number Concept

The coordination number is the number of ligands directly attached to the central metal ion or atom in a coordination compound.
It is a crucial aspect of the structure and properties of coordination compounds.

Role of Ligands in Coordination Compounds

Ligands are neutral molecules or ions that coordinate with a central metal ion or atom to form a coordination compound.
They play a crucial role in determining the coordination number, shape, and properties of the coordination compound.
