Co2AgN3 crystallizes in the trigonal P3_121 space group. Co(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form a mixture of distorted edge and corner-sharing CoN6 octahedra. The corner-sharing octahedral tilt angles range from 9-12°. 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 Co(1) atoms to form NCo6 octahedra that share corners with six equivalent N(2)Co3Ag tetrahedra, edges with six equivalent N(1)Co6 octahedra, and edges with six equivalent N(2)Co3Ag tetrahedra. In the second N site, N(2) is bonded to three equivalent Co(1) and one Ag(1) atom to form distorted NCo3Ag tetrahedra that share corners with three equivalent N(1)Co6 octahedra, corners with seven equivalent N(2)Co3Ag tetrahedra, and edges with three equivalent N(1)Co6 octahedra. The corner-sharing octahedral tilt angles range from 7-15°.
