Materials Data on PrMnSi by Materials Project
PrMnSi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one PrMnSi sheet oriented in the (0, 0, 1) direction. Pr is bonded in a 4-coordinate geometry to four equivalent Si atoms. All Pr–Si bond lengths are 3.03 Å. Mn is bonded to four equivalent Si atoms to form a mixture of distorted corner and edge-sharing MnSi4 tetrahedra. All Mn–Si bond lengths are 2.42 Å. Si is bonded in a 9-coordinate geometry to four equivalent Pr and four equivalent Mn atoms.
