The material described by LaMnN3 crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 7-coordinate geometry to three equivalent N(2) and four equivalent N(1) atoms. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form edge-sharing MnN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to two equivalent La(1) and one Mn(1) atom. In the second N site, N(2) is bonded to three equivalent La(1) and two equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing NLa3Mn2 trigonal bipyramids. is represented by the CIF card [CIF]
