Materials Data on Mn2As by Materials Project
Mn2As crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. there are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a 5-coordinate geometry to five equivalent As atoms. There are one shorter (2.44 Å) and four longer (2.62 Å) Mn–As bond lengths. In the second Mn site, Mn is bonded in a 4-coordinate geometry to four equivalent As atoms. All Mn–As bond lengths are 2.45 Å. As is bonded in a 9-coordinate geometry to nine Mn atoms.
