LaMnN3 crystallizes in the orthorhombic Cmcm space group. La(1) is bonded in a 10-coordinate geometry to four equivalent N(2) and six equivalent N(1) atoms. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing MnN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 1-coordinate geometry to three equivalent La(1) and one Mn(1) atom. In the second N site, N(2) is bonded in a distorted linear geometry to four equivalent La(1) and two equivalent Mn(1) atoms.
LaMnN3 crystallizes in the orthorhombic Cmcm space group. La(1) is bonded in a 10-coordinate geometry to four equivalent N(2) and six equivalent N(1) atoms. All La(1)-N(2) bond lengths are 2.90 Å. There are two shorter (2.56 Å) and four longer (2.84 Å) La(1)-N(1) bond lengths. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing MnN4 tetrahedra. Both Mn(1)-N(1) bond lengths are 1.84 Å. Both Mn(1)-N(2) bond lengths are 1.75 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 1-coordinate geometry to three equivalent La(1) and one Mn(1) atom. In the second N site, N(2) is bonded in a distorted linear geometry to four equivalent La(1) and two equivalent Mn(1) atoms.
