The structure described by Mn3(CrN2)2 crystallizes in the monoclinic C2/c space group. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted CrN4 trigonal pyramids that share corners with four equivalent Mn(1)N4 tetrahedra, corners with two equivalent Cr(1)N4 trigonal pyramids, edges with two equivalent Mn(1)N4 tetrahedra, and  an edgeedge with one Cr(1)N4 trigonal pyramid. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted MnN4 tetrahedra that share corners with two equivalent Mn(1)N4 tetrahedra, corners with four equivalent Cr(1)N4 trigonal pyramids,  an edgeedge with one Mn(1)N4 tetrahedra, and edges with two equivalent Cr(1)N4 trigonal pyramids. In the second Mn site, Mn(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Cr(1), one Mn(2), and two equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing NMn3Cr2 trigonal bipyramids. In the second N site, N(2) is bonded in a 5-coordinate geometry to two equivalent Cr(1), one Mn(2), and two equivalent Mn(1) atoms. is represented by the CIF file [CIF]
