Th2Zn17type
The Th2Zn17 type, also known as the Th2Ni17 structure or simply the 2-17 type, is a crystal structure found in certain intermetallic compounds. This structure is characterized by the chemical formula A2B17, where A is typically a rare earth element, most commonly thorium (Th), and B is a transition metal, often nickel (Ni) or cobalt (Co). The structure can be visualized as layers of the B element interspersed with layers containing both A and B elements.
Compounds with the Th2Zn17 type structure often exhibit interesting magnetic properties. They are frequently ferromagnetic and
The unit cell of the Th2Zn17 structure is typically hexagonal. The arrangement of atoms within this unit
