Abstract:

The orthorhombic B31 structure, typified by MnP, is interpreted as a distortion of the hexagonal NiAs B81 structure due to metal-metal bonding within the hexagonal basal planes. The number of d-like electrons per cation is known from the chemical provided the Fermi level lies in an energy gap between filled and empty bands of broad-band states, as is generally the case where there is a large electronegativity difference between cation and anion.
