The material structure described by LaTcN3 crystallizes in the trigonal R-3c space group. La(1) is bonded to twelve equivalent N(1) atoms to form distorted LaN12 cuboctahedra that share corners with twelve equivalent La(1)N12 cuboctahedra, faces with six equivalent La(1)N12 cuboctahedra, and faces with eight equivalent Tc(1)N6 octahedra. Tc(1) is bonded to six equivalent N(1) atoms to form TcN6 octahedra that share corners with six equivalent Tc(1)N6 octahedra and faces with eight equivalent La(1)N12 cuboctahedra. The corner-sharing octahedral tilt angles are 15°. N(1) is bonded in a 6-coordinate geometry to four equivalent La(1) and two equivalent Tc(1) atoms. is represented by the CIF card [CIF]
