The Complexes compounds in which all the ligands are bound to the metal center which are identical to each other are known as homoleptic complexes and the complexes in which the metal atoms or ions are linked with more than one kind of ligands are known as heteroleptic complexes.

What are Homoleptic and Heteroleptic complexes?
homoleptic complex are those which has only one type ligand. heteroleptic complex are those which has more than one type of ligand.
What are Homoleptic and Heteroleptic complexes give examples?
Homoleptic complexes : These are the complexes in which a metal is bound by only ore kind of ligands eg. : [ Co(NH3)6]3+ Heteroleptic complexes : These are the complexes iri which a metal is bound by more than one kind of ligends eg. :[ Co(NH3)4]Cl2]+ Answer.
Is metal carbonyl Homoleptic or Heteroleptic complex?
These complexes may be homoleptic, containing only CO ligands, such as nickel tetracarbonyl (Ni(CO)4), but more commonly metal carbonyls are heteroleptic and contain a mixture of ligands. Mononuclear metal carbonyls contain only one metal atom as the central atom.
What are mononuclear complexes?
coordination compounds
In coordination compound: Mononuclear, monodentate. The simplest types of coordination compounds are those containing a single metal atom or ion (mononuclear compounds) surrounded by monodentate ligands. Most of the coordination compounds already cited belong to this class.
What are Homoleptic complexes give example?
Homoleptic Complexes are compounds in which all the ligands bound to the metal center are identical. Some examples are given below: There are some who believe that the word is not really necessary -- for example, the term "binary metal carbonyl" has long been used to describe a homoleptic carbonyl compound.
Why are metal complexes Coloured?
When ligands attach to a transition metal to form a coordination complex, electrons in the d orbital split into high energy and low energy orbitals. ... As certain wavelengths are absorbed in this process, subtractive color mixing occurs and the coordination complex solution becomes colored.
Which of the following complexes are Homoleptic?
Solution : Homopleptic complex The complex containing only one species or group as ligand is known as homoleptic ligand. Here, [Co(NH3)6]3+ contain only NH3 as a ligand and [Ni(CN)4]2- contain CN as a ligand. While other two complexes [Co(NH3)4Cl2]+ and [Ni(NH3)4Cl2] contain NH3 and Cl as ligands.
Which of the following complexes are Heteroleptic?
Heteropleptic complexes Coordination complexes which contain more than one type of ligands are known as heteropletic complexes. e.g., [Fe(NH3)4Cl2]+ contain NH3 and Cl as a ligand is as heteroleptic complex. Similarly [Co(NH3)4Cl2] contain NH3 and Cl as ligand is also a heteroleptic complex.
What is Ambidentate ligand?
Ambidentate ligand is a type of ligands which have the ability to bind to the central atom via the atoms of two different elements. Examples: thiocyanate ion(NCS–) which can bind to the central metal atom or ion with either nitrogen or sulfur atoms.
Which is the strongest field ligand?
The more electropositive C atom in the strong field ligand CN- allows better orbital overlap and sharing of the electron pair. Note that CN- typically coordinates metal ions through the C atom rather than the N atom.
What are metal carbonyls give example?
Metal carbonyl, any coordination or complex compound consisting of a heavy metal such as nickel, cobalt, or iron surrounded by carbonyl (CO) groups. Some common metal carbonyls include: tetracarbonylnickel Ni(CO)4, pentacarbonyliron Fe(CO)5, and octacarbonyldicobalt Co2(CO)8.
Why is PT 4 unstable?
The main reason why Pd(CO)4 and Pt(CO)4 are unstable at room temperature in a condensed phase can be traced back to the already rather weak bond energy of the Ni‐CO bond. ... The first bond dissociation energy of Pt(CO)4 is low because the relaxation energy of the Pt(CO)3 fragment is rather high.
