LaTcN3 crystallizes in the monoclinic P2/m space group. La(1) is bonded in a distorted body-centered cubic geometry to two equivalent N(1), two equivalent N(2), two equivalent N(3), and two equivalent N(4) atoms. Tc(1) is bonded in a rectangular see-saw-like geometry to one N(1), one N(2), one N(3), and one N(4) atom. There are four inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to two equivalent La(1), one Tc(1), and one N(2) atom. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent La(1), one Tc(1), and one N(1) atom. In the third N site, N(3) is bonded to four equivalent La(1) and two equivalent Tc(1) atoms to form a mixture of face, corner, and edge-sharing NLa4Tc2 octahedra. The corner-sharing octahedral tilt angles are 61°. In the fourth N site, N(4) is bonded to four equivalent La(1) and two equivalent Tc(1) atoms to form a mixture of face, corner, and edge-sharing NLa4Tc2 octahedra. The corner-sharing octahedral tilt angles are 61°.
