(a) The MnP structure projected on the ab plane. The Mn atoms are green spheres and violet spheres represent the P atoms. By inserting an additional atom (golden sphere) this structure converts into the Co2Si-type structure projected in (b). Co atoms form the trigonal prisms and are represented as orange spheres and the Si atoms as grey spheres. Note that the P atoms in (a) are equivalent to the Si atoms in (b). |
