Ti2AgN3 crystallizes in the trigonal P3_121 space group. Ti(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form a mixture of corner and edge-sharing TiN6 octahedra. The corner-sharing octahedra are not tilted. Ag(1) is bonded in a linear geometry to two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to six equivalent Ti(1) atoms to form NTi6 octahedra that share corners with six equivalent N(2)Ti3Ag tetrahedra, edges with six equivalent N(1)Ti6 octahedra, and edges with six equivalent N(2)Ti3Ag tetrahedra. In the second N site, N(2) is bonded to three equivalent Ti(1) and one Ag(1) atom to form NTi3Ag tetrahedra that share corners with three equivalent N(1)Ti6 octahedra, corners with seven equivalent N(2)Ti3Ag tetrahedra, and edges with three equivalent N(1)Ti6 octahedra. The corner-sharing octahedral tilt angles are 10°.
