The material described by HfMnN2 crystallizes in the orthorhombic Pnma space group. Hf(1) is bonded to two equivalent N(2) and three equivalent N(1) atoms to form HfN5 trigonal bipyramids that share corners with four equivalent Hf(1)N5 trigonal bipyramids, corners with four equivalent Mn(1)N5 trigonal bipyramids, edges with two equivalent Hf(1)N5 trigonal bipyramids, and edges with four equivalent Mn(1)N5 trigonal bipyramids. Mn(1) is bonded to two equivalent N(1) and three equivalent N(2) atoms to form MnN5 trigonal bipyramids that share corners with four equivalent Hf(1)N5 trigonal bipyramids, corners with four equivalent Mn(1)N5 trigonal bipyramids, edges with two equivalent Mn(1)N5 trigonal bipyramids, and edges with four equivalent Hf(1)N5 trigonal bipyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Hf(1) and two equivalent Mn(1) atoms to form NHf3Mn2 trigonal bipyramids that share corners with four equivalent N(2)Hf2Mn3 trigonal bipyramids, corners with four equivalent N(1)Hf3Mn2 trigonal bipyramids, edges with two equivalent N(1)Hf3Mn2 trigonal bipyramids, and edges with four equivalent N(2)Hf2Mn3 trigonal bipyramids. In the second N site, N(2) is bonded to two equivalent Hf(1) and three equivalent Mn(1) atoms to form NHf2Mn3 trigonal bipyramids that share corners with four equivalent N(2)Hf2Mn3 trigonal bipyramids, corners with four equivalent N(1)Hf3Mn2 trigonal bipyramids, edges with two equivalent N(2)Hf2Mn3 trigonal bipyramids, and edges with four equivalent N(1)Hf3Mn2 trigonal bipyramids. is represented by the CIF card [CIF]
