Single crystal growth of Mn2N using an In–Na flux

Hexagonal platelet and pyramidal single crystals of Mn2N were prepared by using an In–Na flux at 700 °C and 5 MPa of N2 pressure. The crystal structure (space group P63/mmc) with lattice parameters a=2.8185(6) Å and c=4.5371(12) Å was confirmed by X-ray single-crystal diffraction. Nitrogen atoms statistically occupy a half of the octahedral interstitial sites in a hexagonal closest packing arrangement of Mn atoms.
