Mn3(InN2)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted trigonal non-coplanar geometry to one In(1), one N(2), and two equivalent N(1) atoms. In the second Mn site, Mn(2) is bonded in a distorted tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. In(1) is bonded in a 4-coordinate geometry to one Mn(1) and three equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. In the second N site, N(2) is bonded to one Mn(1), one Mn(2), and three equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing NMn2In3 trigonal bipyramids.

In the first Mn site, Mn(1) is bonded in a distorted trigonal non-coplanar geometry to one In(1), one N(2), and two equivalent N(1) atoms. The Mn(1)-In(1) bond length is 2.66 Å. The Mn(1)-N(2) bond length is 1.85 Å. There is one shorter (1.77 Å) and one longer (1.82 Å) Mn(1)-N(1) bond length. In the second Mn site, Mn(2) is bonded in a distorted tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Mn(2)-N(1) bond lengths are 1.88 Å. Both Mn(2)-N(2) bond lengths are 1.91 Å. In(1) is bonded in a 4-coordinate geometry to one Mn(1) and three equivalent N(2) atoms. There are a spread of In(1)-N(2) bond distances ranging from 2.25-2.56 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. In the second N site, N(2) is bonded to one Mn(1), one Mn(2), and three equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing NMn2In3 trigonal bipyramids.
