SrWN3 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(3), two equivalent N(2), and three equivalent N(1) atoms. W(1) is bonded in a 5-coordinate geometry to one N(1), one N(2), and three equivalent N(3) atoms. There are three inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Sr(1) and one W(1) atom to form distorted NSr3W trigonal pyramids that share corners with five equivalent N(2)Sr2WN tetrahedra, corners with two equivalent N(1)Sr3W trigonal pyramids, corners with four equivalent N(3)SrW3 trigonal pyramids,  an edgeedge with one N(2)Sr2WN tetrahedra,  an edgeedge with one N(3)SrW3 trigonal pyramid, and edges with two equivalent N(1)Sr3W trigonal pyramids. In the second N site, N(2) is bonded to two equivalent Sr(1), one W(1), and one N(2) atom to form distorted NSr2WN tetrahedra that share corners with two equivalent N(2)Sr2WN tetrahedra, corners with five equivalent N(1)Sr3W trigonal pyramids, corners with five equivalent N(3)SrW3 trigonal pyramids, and  an edgeedge with one N(1)Sr3W trigonal pyramid. In the third N site, N(3) is bonded to one Sr(1) and three equivalent W(1) atoms to form distorted NSrW3 trigonal pyramids that share corners with five equivalent N(2)Sr2WN tetrahedra, corners with two equivalent N(3)SrW3 trigonal pyramids, corners with four equivalent N(1)Sr3W trigonal pyramids,  an edgeedge with one N(1)Sr3W trigonal pyramid, and edges with two equivalent N(3)SrW3 trigonal pyramids.
SrWN3 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(3), two equivalent N(2), and three equivalent N(1) atoms. The Sr(1)-N(3) bond length is 2.70 Å. Both Sr(1)-N(2) bond lengths are 2.64 Å. There are two shorter (2.60 Å) and one longer (2.74 Å) Sr(1)-N(1) bond length. W(1) is bonded in a 5-coordinate geometry to one N(1), one N(2), and three equivalent N(3) atoms. The W(1)-N(1) bond length is 1.78 Å. The W(1)-N(2) bond length is 1.94 Å. There are two shorter (2.04 Å) and one longer (2.08 Å) W(1)-N(3) bond length. There are three inequivalent N sites.
