Materials Data on La(MnGe)2 by Materials Project

Kristin Persson
LaMn2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. La is bonded in a 8-coordinate geometry to eight equivalent Ge atoms. All La–Ge bond lengths are 3.20 Å. Mn is bonded to four equivalent Ge atoms to form a mixture of edge and corner-sharing MnGe4 tetrahedra. All Mn–Ge bond lengths are 2.45 Å. Ge is bonded in a 9-coordinate geometry to four equivalent La, four equivalent Mn, and one Ge atom. The...
