Materials Data on Mn2P by Materials Project
Mn2P crystallizes in the trigonal P321 space group. The structure is three-dimensional. there are two inequivalent Mn sites. In the first Mn site, Mn is bonded to four P atoms to form a mixture of distorted corner and edge-sharing MnP4 tetrahedra. There are two shorter (2.26 Å) and two longer (2.30 Å) Mn–P bond lengths. In the second Mn site, Mn is bonded in a 5-coordinate geometry to five P atoms. There are one shorter (2.44 Å) and four longer (2.47 Å) Mn–P bond lengths. There are two inequivalent P sites. In the first P site, P is bonded in a 9-coordinate geometry to nine Mn atoms. In the second P site, P is bonded in a 9-coordinate geometry to nine Mn atoms.
