Cr3AsN crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted bent 150 degrees geometry to two equivalent As(1) and two equivalent N(1) atoms. In the second Cr site, Cr(2) is bonded in a linear geometry to four equivalent As(1) and two equivalent N(1) atoms. As(1) is bonded in a 8-coordinate geometry to four equivalent Cr(1) and four equivalent Cr(2) atoms. N(1) is bonded to two equivalent Cr(2) and four equivalent Cr(1) atoms to form corner-sharing NCr6 octahedra. The corner-sharing octahedral tilt angles range from 0-30°.

In the first Cr site, Cr(1) is bonded in a distorted bent 150 degrees geometry to two equivalent As(1) and two equivalent N(1) atoms. Both Cr(1)-As(1) bond lengths are 2.42 Å. Both Cr(1)-N(1) bond lengths are 1.95 Å. In the second Cr site, Cr(2) is bonded in a linear geometry to four equivalent As(1) and two equivalent N(1) atoms. All Cr(2)-As(1) bond lengths are 2.67 Å. Both Cr(2)-N(1) bond lengths are 1.98 Å. As(1) is bonded in a 8-coordinate geometry to four equivalent Cr(1) and four equivalent Cr(2) atoms. N(1) is bonded to two equivalent Cr(2) and four equivalent Cr(1) atoms to form corner-sharing NCr6 octahedra. The corner-sharing octahedral tilt angles range from 0-30°.
