The strong bonding of metals in liquid form demonstrates that the energy of a metallic bond is not highly dependent on the direction of the bond; this lack of bond directionality is a direct consequence of electron delocalization, and is best understood in contrast to the directional bonding of covalent bonds.
In chemistry, a metallophilic interaction is defined as a type of non-covalent attraction between heavy metal atoms. The atoms are often within Van der Waals distance of each other and are about as strong as hydrogen bonds. [1] The effect can be intramolecular or intermolecular.
Metallic solids have, by definition, no band gap at the Fermi level and hence are conducting. Solids with purely metallic bonding are characteristically ductile and, in their pure forms, have low strength; melting points can [inconsistent] be very low (e.g., Mercury melts at 234 K (−39 °C)). These properties are consequences of the non ...
Rather, bond types are interconnected and different compounds have varying degrees of different bonding character (for example, covalent bonds with significant ionic character are called polar covalent bonds). Six years later, in 1947, Ketelaar developed van Arkel's idea by adding more compounds and placing bonds on different sides of the triangle.
A less often mentioned type of bonding is metallic bonding. In this type of bonding, each atom in a metal donates one or more electrons to a "sea" of electrons that reside between many metal atoms. In this sea, each electron is free (by virtue of its wave nature) to be associated with a great many atoms at once. The bond results because the ...

An example of a metal–metal bond is found in dimanganese decacarbonyl, Mn 2 (CO) 10. As confirmed by X-ray crystallography, a pair of Mn(CO) 5 units are linked by a bond between the Mn atoms. The Mn-Mn distance (290 pm) is short. [3] Mn 2 (CO) 10 is a simple and clear case of a metal-metal bond because no other atoms tie the two Mn atoms ...
Metallic structure consists of aligned positive ions in a "sea" of delocalized electrons. This means that the electrons are free to move throughout the structure, and gives rise to properties such as conductivity. In diamond all four outer electrons of each carbon atom are 'localized' between the atoms in covalent bonding. The movement of ...
