The structure described by SrWN3 crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to one N(1), one N(4), two equivalent N(2), two equivalent N(3), and two equivalent N(5) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to one N(1), one N(4), two equivalent N(3), two equivalent N(5), and two equivalent N(6) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one N(2), one N(5), one N(6), and two equivalent N(1) atoms to form distorted corner-sharing WN5 trigonal bipyramids. In the second W site, W(2) is bonded in a 5-coordinate geometry to one N(2), one N(3), one N(6), and two equivalent N(4) atoms. There are six inequivalent N sites. In the first N site, N(1) is bonded to one Sr(1), one Sr(2), and two equivalent W(1) atoms to form distorted NSr2W2 trigonal pyramids that share corners with two equivalent N(1)Sr2W2 trigonal pyramids and edges with two equivalent N(2)Sr2W2N trigonal bipyramids. In the second N site, N(2) is bonded to two equivalent Sr(1), one W(1), one W(2), and one N(4) atom to form distorted NSr2W2N trigonal bipyramids that share corners with two equivalent N(2)Sr2W2N trigonal bipyramids and edges with two equivalent N(1)Sr2W2 trigonal pyramids. In the third N site, N(3) is bonded in a 5-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and one W(2) atom. In the fourth N site, N(4) is bonded in a 5-coordinate geometry to one Sr(1), one Sr(2), two equivalent W(2), and one N(2) atom. In the fifth N site, N(5) is bonded in a 5-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and one W(1) atom. In the sixth N site, N(6) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Sr(2), one W(1), and one W(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
