Mn3InN3 crystallizes in the monoclinic P2_1/m space group. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a trigonal planar geometry to two equivalent In(1), one N(3), and two equivalent N(1) atoms. In the second Mn site, Mn(2) is bonded in a trigonal planar geometry to two equivalent In(1), one N(1), and two equivalent N(2) atoms. In the third Mn site, Mn(3) is bonded in a trigonal planar geometry to two equivalent In(1), one N(2), and two equivalent N(3) atoms. In(1) is bonded in a 11-coordinate geometry to two equivalent Mn(1), two equivalent Mn(2), two equivalent Mn(3), two equivalent In(1), one N(1), one N(2), and one N(3) atom. There are three inequivalent N sites. In the first N site, N(1) is bonded in a trigonal non-coplanar geometry to one Mn(2), two equivalent Mn(1), and one In(1) atom. In the second N site, N(2) is bonded in a trigonal non-coplanar geometry to one Mn(3), two equivalent Mn(2), and one In(1) atom. In the third N site, N(3) is bonded in a trigonal non-coplanar geometry to one Mn(1), two equivalent Mn(3), and one In(1) atom.
