Metal-Ligand Bonds02:51

Metal-Ligand Bonds

19.3K
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Metallic Solids

16.4K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and...

Properties of Organometallic Compounds

2.1K
Organometallic compounds are compounds that contain a carbon–metal bond. Carbon belongs to an organyl group like alkyl, aryl, allyl, or benzyl groups. The metal can be from Group I or Group II of the periodic table, a transition metal, or a semimetal.

Bonding in Metals

45.6K
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Valence Bond Theory02:42

Valence Bond Theory

8.9K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Properties of Transition Metals02:58

Properties of Transition Metals

28.2K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

  • Synthesized dopant@metal materials via aqueous reductions, electrochemical entrapment, thermal decomposition, and amalgam formation.
  • Characterized the porous nanocrystalline structure of dopant@metal materials, ensuring dopant accessibility.

    • Main Results:

    • Successfully created dopant@metal materials with altered classical metal properties (e.g., conductivity) and induced unorthodox properties (e.g., acidity/basicity).
    • Demonstrated applications including heterogeneous catalysis, bioactive metals, chiral materials, corrosion-resistant iron, biocidal agents, and battery concepts.
    • Confirmed that entrapment, unlike adsorption, permanently integrates dopants, leading to unique material behaviors.

    Conclusions:

    • The dopant@metal methodology offers a powerful approach to designing advanced materials with tailored properties.
    • These hybrid materials bridge the gap between metals and molecular functionalities, opening new avenues in various scientific and technological fields.
    • The unique porous structure and permanent dopant entrapment are key to the observed enhanced and novel properties.
