Metallides are chemical compounds (usually metal - metal, such compounds are called intermetallic , less commonly transition metal - non - metal ), characterized by a metallic type of bond . In such compounds, the rule of formal valency is not observed, they have a high melting point (often higher than that of the individual components), they are bertollides .
Metallic Examples
- Metal - metal: Cu 9 Al 4 .
- Metal - Non-Metal: Ti 6 O.
- Compounds, the nature of the bond in which may be metallic or ionic depending on the composition: GaAs , NiAs .
