The structure described by Ba3Os3N5 crystallizes in the triclinic P-1 space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 4-coordinate geometry to one N(3), one N(4), one N(5), and two equivalent N(2) atoms. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to one N(1), one N(3), one N(4), and three equivalent N(5) atoms. In the third Ba site, Ba(3) is bonded in a 4-coordinate geometry to one N(1), one N(2), one N(3), and one N(4) atom. There are three inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted rectangular see-saw-like geometry to one N(1), one N(5), and two equivalent N(3) atoms. In the second Os site, Os(2) is bonded in a distorted T-shaped geometry to one N(1), one N(2), and one N(4) atom. In the third Os site, Os(3) is bonded in a trigonal planar geometry to one N(2), one N(4), and one N(5) atom. There are five inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to one Ba(2), one Ba(3), one Os(1), and one Os(2) atom. In the second N site, N(2) is bonded to one Ba(3), two equivalent Ba(1), one Os(2), and one Os(3) atom to form distorted edge-sharing NBa3Os2 trigonal bipyramids. In the third N site, N(3) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), one Ba(3), and two equivalent Os(1) atoms. In the fourth N site, N(4) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), one Ba(3), one Os(2), and one Os(3) atom. In the fifth N site, N(5) is bonded in a 6-coordinate geometry to one Ba(1), three equivalent Ba(2), one Os(1), and one Os(3) atom. is represented by the CIF file [CIF]
