TaMn2N3 crystallizes in the orthorhombic Cmc2_1 space group. Ta(1) is bonded to two equivalent N(1) and three equivalent N(2) atoms to form a mixture of corner and edge-sharing TaN5 trigonal bipyramids. Mn(1) is bonded in a 4-coordinate geometry to one N(2) and three equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(2) is bonded to three equivalent Ta(1) and two equivalent Mn(1) atoms to form a mixture of corner and edge-sharing NTa3Mn2 trigonal bipyramids. In the second N site, N(1) is bonded in a 4-coordinate geometry to one Ta(1) and three equivalent Mn(1) atoms.
