Ba3(RuN2)2 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 5-coordinate geometry to two equivalent N(1) and three equivalent N(2) atoms. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. In the second Ru site, Ru(2) is bonded in a distorted trigonal pyramidal geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), one Ru(1), and one Ru(2) atom. In the second N site, N(2) is bonded to one Ba(2), three equivalent Ba(1), one Ru(1), and one Ru(2) atom to form a mixture of distorted face, corner, and edge-sharing NBa4Ru2 octahedra. The corner-sharing octahedral tilt angles range from 39-68°.
