The compound described by CrMnN2 crystallizes in the orthorhombic Pna2_1 space group. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted CrN4 tetrahedra that share corners with four equivalent Cr(1)N4 tetrahedra and corners with eight equivalent Mn(1)N4 trigonal pyramids. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted MnN4 trigonal pyramids that share corners with eight equivalent Cr(1)N4 tetrahedra and corners with four equivalent Mn(1)N4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Cr(1) and two equivalent Mn(1) atoms to form corner-sharing NMn2Cr2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Cr(1) and two equivalent Mn(1) atoms to form corner-sharing NMn2Cr2 trigonal pyramids. is represented by the CIF card [CIF]
