SrTcN3 is Aluminum carbonitride-like structured and crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 6-coordinate geometry to one N(1), two equivalent N(2), and three equivalent N(3) atoms. Tc(1) is bonded to one N(2), one N(3), and three equivalent N(1) atoms to form distorted TcN5 trigonal bipyramids that share  a cornercorner with one N(2)Sr2TcN tetrahedra, corners with two equivalent Tc(1)N5 trigonal bipyramids, and edges with two equivalent Tc(1)N5 trigonal bipyramids. There are three inequivalent N sites. In the first N site, N(1) is bonded to one Sr(1) and three equivalent Tc(1) atoms to form distorted NSrTc3 tetrahedra that share corners with two equivalent N(1)SrTc3 tetrahedra, corners with five equivalent N(2)Sr2TcN tetrahedra, corners with four equivalent N(3)Sr3Tc trigonal pyramids, edges with two equivalent N(1)SrTc3 tetrahedra, and  an edgeedge with one N(3)Sr3Tc trigonal pyramid. In the second N site, N(2) is bonded to two equivalent Sr(1), one Tc(1), and one N(2) atom to form distorted NSr2TcN tetrahedra that share corners with two equivalent N(2)Sr2TcN tetrahedra, corners with five equivalent N(1)SrTc3 tetrahedra,  a cornercorner with one Tc(1)N5 trigonal bipyramid, corners with five equivalent N(3)Sr3Tc trigonal pyramids, and  an edgeedge with one N(3)Sr3Tc trigonal pyramid. In the third N site, N(3) is bonded to three equivalent Sr(1) and one Tc(1) atom to form distorted NSr3Tc trigonal pyramids that share corners with four equivalent N(1)SrTc3 tetrahedra, corners with five equivalent N(2)Sr2TcN tetrahedra, corners with two equivalent N(3)Sr3Tc trigonal pyramids,  an edgeedge with one N(2)Sr2TcN tetrahedra,  an edgeedge with one N(1)SrTc3 tetrahedra, and edges with two equivalent N(3)Sr3Tc trigonal pyramids.
SrTcN3 is Aluminum carbonitride-like structured and crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 6-coordinate geometry to one N(1), two equivalent N(2), and three equivalent N(3) atoms. The Sr(1)-N(1) bond length is 2.63 Å. Both Sr(1)-N(2) bond lengths are 2.65 Å. There are two shorter (2.56 Å) and one longer (2.76 Å) Sr(1)-N(3) bond length. Tc(1) is bonded to one N(2), one N(3), and three equivalent N(1) atoms to form distorted TcN5 trigonal bipyramids that share  a cornercorner with one N(2)Sr2TcN tetrahedra, corners with two equivalent Tc(1)N5 trigonal bipyramids, and edges with two equivalent Tc(1)N5 trigonal bipyramids. The Tc(1)-N(2) bond length is 1.98 Å. The Tc(1)-N(3) bond length is 1.73 Å. There is one shorter (1.99 Å) and two longer (2.05 Å) Tc(1)-N(1) bond lengths. There are three inequivalent N sites.
