Materials Data on LaTcN3 by Materials Project
LaTcN3 is Esseneite-derived structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to six N3- atoms to form LaN6 octahedra that share corners with six equivalent TcN4 tetrahedra and edges with two equivalent LaN6 octahedra. There are a spread of La–N bond distances ranging from 2.38–2.64 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to six N3- atoms. There are a spread of La–N bond distances ranging from 2.47–2.71 Å. Tc6+ is bonded to four N3- atoms to form TcN4 tetrahedra that share corners with three equivalent LaN6 octahedra and corners with two equivalent TcN4 tetrahedra. The corner-sharing octahedra tilt angles range from 39–71°. There are a spread of Tc–N bond distances ranging from 1.80–1.92 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a 4-coordinate geometry to three La3+ and one Tc6+ atom. In the second N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to two La3+ and one Tc6+ atom. In the third N3- site, N3- is bonded in a 2-coordinate geometry to one La3+ and two equivalent Tc6+ atoms.
