Manganese phosphide is an inorganic chemical compound of manganese from the group of phosphides .
Extraction and presentation
Manganese phosphide can be obtained by electrolysis of manganese with phosphorus or by reaction of manganese and calcium phosphide at elevated temperatures.
properties
Manganese phosphide is a solid that is in the form of shiny metallic needles and that is practically insoluble in water. It is a p-type semiconductor . It has an orthorhombic crystal structure with the space group Pnma (space group no. 62) . In the structure there are zigzag chains of manganese and phosphorus atoms. In addition, there are Mn – Mn bonds between adjacent chains. The interesting magnetic properties at low temperatures led to intensive research into the compound.
use
Manganese phosphides are used in biochemistry for proteome research .
