Most metal carbonyl complexes contain a mixture of ligands. Examples include the historically important IrCl(CO)(P(C 6 H 5) 3) 2 and the antiknock agent (CH 3 C 5 H 4)Mn(CO) 3. The parent compounds for many of these mixed ligand complexes are the binary carbonyls, those species of the formula [M x (CO) n] z, many of which are
Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond .
Iron pentacarbonyl, also known as iron carbonyl, is the compound with formula Fe(C O) 5. Under standard conditions Fe 5 is a free-flowing, straw-colored liquid with a pungent odour. Older samples appear darker. This compound is a common precursor to diverse iron compounds, including many that are useful in small scale organic synthesis. [2]
In the covalent bond classification method, κ 1-carbonate is anX ligand and κ 2-carbonate is an X 2 ligand. With two metals, the number of bonding modes increases because carbonate often serves as a bridging ligand. It can span metal-metal bonds as in [Ru 2 (CO 3) 4 Cl 2] 5-, where again it functions as an (X) 2 ligand.

The main structure of chemical names according to IUPAC nomenclature. IUPAC nomenclature is a set of recommendations for naming chemical compounds and for describing chemistry and biochemistry in general. The International Union of Pure and Applied Chemistry (IUPAC) is the international authority on chemical nomenclature and terminology.
Ligand selection requires critical consideration in many practical areas, including bioinorganic and medicinal chemistry, homogeneous catalysis, and environmental chemistry. Ligands are classified in many ways, including: charge, size (bulk), the identity of the coordinating atom(s), and the number of electrons donated to the metal ( denticity ...
Ligands may bridge two or more centres. The prefix μ is used to specify a bridging ligand in both the formula and the name. For example the dimeric form of aluminium trichloride: Al 2 Cl 4 (μ-Cl) 2 di-μ-chlorido-tetrachlorido-1κ 2 Cl,2κ 2 Cl-dialuminium. This example illustrates the ordering of bridging and non bridging ligands of the same ...
