  • Organometallic compound | Definition, Examples, Preparation . . .
    Organometallic compound, any member of a class of substances containing at least one metal-to-carbon bond in which the carbon is part of an organic group Organometallic compounds constitute a very large group of substances that have played a major role in the development of the science of
  • Organometallic compound - Synthesis, Reactivity, Applications | Britannica
    Organometallic compound - Synthesis, Reactivity, Applications: groups in organometallic chemistryA compound is regarded as organometallic if it contains at least one metal-carbon (M―C) bond where the carbon is part of an organic group Typically, an organic group contains carbon-hydrogen (C―H) bonds; for example, the simple methyl group, CH3, and larger homologs such as the ethyl group
  • Organometallic compound - Stability, Reactivity, Bonding | Britannica
    Organometallic compound - Stability, Reactivity, Bonding: The stability and reactivity of organometallic compounds are associated with the nature of the organic ligands and the metal to which they are attached In each of the main groups of the periodic table (groups 1, 2, and 13–15), the thermal stability of a given type of organometallic compound generally decreases from the lightest to
  • Organometallic compound - Carbanion Character, Bonding, Reactivity . . .
    Organometallic compound - Carbanion Character, Bonding, Reactivity: The partial negative charge of an organic group bonded to a highly active metal results in a distinctive pattern of reactivity that is frequently referred to as nucleophilic or carbanion character Thus, organometallic compounds containing highly active (electropositive) metals, such as lithium, magnesium, aluminum, and zinc
  • Organometallic compound - Metal Clusters | Britannica
    Organometallic compound - Metal Clusters: Metal cluster compounds contain metal-metal bonds The focus here is on compounds having three or more metals in a closed array Carbon monoxide is the most common ligand in organometallic cluster compounds, but many other organometallic ligands are bound to clusters, and the presence of several metals leads to bonding arrangements for the ligand that
  • Organometallic compound - Alkene, Alkyne, Ligands | Britannica
    Organometallic compound - Alkene, Alkyne, Ligands: An alkene ligand contains a π bond between carbon atoms, C=C, which can serve as an electron pair donor in a metal complex, as in the case of Zeise’s salt (see above Historical developments) This complex may be prepared by bubbling ethylene, C2H4, through an aqueous solution of [PtCl4]2− in the presence of divalent tin, Sn (II), which
  • organometallic compound summary | Britannica
    organometallic compound, Any member of a class of substances containing at least one metal-to-carbon bond in which the carbon is part of an organic group
  • Grignard reagent | Organic Synthesis, Organometallic Compounds . . .
    Grignard reagent, any of numerous organic derivatives of magnesium (Mg) commonly represented by the general formula RMgX (in which R is a hydrocarbon radical: CH3, C2H5, C6H5, etc ; and X is a halogen atom, usually chlorine, bromine, or iodine) They are called Grignard reagents after their
  • Organometallic compound - Metal Carbonyl, Anions | Britannica
    Organometallic compound - Metal Carbonyl, Anions: More remarkable than the formation of zero-oxidation-state metal carbonyls is the reduction of many of these carbonyl compounds to metal carbonyl anions, in which the metal has a negative oxidation state The following example demonstrates that the two-electron reduction by sodium metal is accompanied by the loss of the two-electron donor
