Cyclopentadienylcobalt dicarbonyl is an organocobalt compound with formula (C 5 H 5)Co(CO) 2, abbreviated CpCo(CO) 2. It is an example of a half-sandwich complex. It is a dark red air sensitive liquid. This compound features one cyclopentadienyl ring that is bound in an η 5-manner and two carbonyl ligands. The compound is soluble in common ...
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 .
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
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.
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 ...
The bent NO ligand is sometimes described as the anion, NO −. Prototypes for such compounds are the organic nitroso compounds, such as nitrosobenzene. A complex with a bent NO ligand is trans-[Co 2 (NO)Cl] +. The NO − is also common for alkali-metal or alkaline-earth metal-NO molecules. For example.
