LiRu2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Li(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form LiN4 tetrahedra that share corners with two equivalent Li(1)N4 tetrahedra and corners with ten equivalent Ru(1)N4 tetrahedra. Ru(1) is bonded to one N(2) and three equivalent N(1) atoms to form RuN4 tetrahedra that share corners with five equivalent Li(1)N4 tetrahedra and corners with seven equivalent Ru(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent Li(1) and two equivalent Ru(1) atoms to form NLi2Ru2 tetrahedra that share corners with two equivalent N(2)Li2Ru2 tetrahedra and corners with ten equivalent N(1)LiRu3 tetrahedra. In the second N site, N(1) is bonded to one Li(1) and three equivalent Ru(1) atoms to form NLiRu3 tetrahedra that share corners with five equivalent N(2)Li2Ru2 tetrahedra and corners with seven equivalent N(1)LiRu3 tetrahedra.

Li(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form LiN4 tetrahedra that share corners with two equivalent Li(1)N4 tetrahedra and corners with ten equivalent Ru(1)N4 tetrahedra. Both Li(1)-N(1) bond lengths are 2.14 Å. There is one shorter (2.09 Å) and one longer (2.16 Å) Li(1)-N(2) bond length. Ru(1) is bonded to one N(2) and three equivalent N(1) atoms to form RuN4 tetrahedra that share corners with five equivalent Li(1)N4 tetrahedra and corners with seven equivalent Ru(1)N4 tetrahedra. The Ru(1)-N(2) bond length is 1.88 Å. There are a spread of Ru(1)-N(1) bond distances ranging from 1.94-1.96 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent Li(1) and two equivalent Ru(1) atoms to form NLi2Ru2 tetrahedra that share corners with two equivalent N(2)Li2Ru2 tetrahedra and corners with ten equivalent N(1)LiRu3 tetrahedra.
