Cd3(InN2)2 is Chalcostibite-like structured and crystallizes in the monoclinic C2/c space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. In the second Cd site, Cd(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CdN4 tetrahedra that share corners with eight equivalent In(1)N4 tetrahedra. In(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted InN4 tetrahedra that share corners with two equivalent In(1)N4 tetrahedra, corners with four equivalent Cd(2)N4 tetrahedra, and  an edgeedge with one In(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Cd(2), two equivalent Cd(1), and two equivalent In(1) atoms to form distorted NCd3In2 trigonal bipyramids that share corners with eight equivalent N(2)Cd2In2 tetrahedra,  a cornercorner with one N(1)Cd3In2 trigonal bipyramid, and edges with two equivalent N(1)Cd3In2 trigonal bipyramids. In the second N site, N(2) is bonded to one Cd(1), one Cd(2), and two equivalent In(1) atoms to form distorted NCd2In2 tetrahedra that share corners with three equivalent N(2)Cd2In2 tetrahedra and corners with eight equivalent N(1)Cd3In2 trigonal bipyramids.

In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. The Cd(1)-N(2) bond length is 2.19 Å. There is one shorter (2.20 Å) and one longer (2.45 Å) Cd(1)-N(1) bond length. In the second Cd site, Cd(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CdN4 tetrahedra that share corners with eight equivalent In(1)N4 tetrahedra. Both Cd(2)-N(1) bond lengths are 2.41 Å. Both Cd(2)-N(2) bond lengths are 2.33 Å. In(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted InN4 tetrahedra that share corners with two equivalent In(1)N4 tetrahedra, corners with four equivalent Cd(2)N4 tetrahedra, and  an edgeedge with one In(1)N4 tetrahedra. There is one shorter (2.20 Å) and one longer (2.26 Å) In(1)-N(1) bond length. There is one shorter (2.19 Å) and one longer (2.22 Å) In(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Cd(2), two equivalent Cd(1), and two equivalent In(1) atoms to form distorted NCd3In2 trigonal bipyramids that share corners with eight equivalent N(2)Cd2In2 tetrahedra,  a cornercorner with one N(1)Cd3In2 trigonal bipyramid, and edges with two equivalent N(1)Cd3In2 trigonal bipyramids.
