Materials Data on LiNbAs2 by Materials Project
LiNbAs2 is Enargite-like structured and crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Li1+ is bonded to four equivalent As3- atoms to form LiAs4 tetrahedra that share corners with four equivalent LiAs4 tetrahedra and corners with eight equivalent NbAs4 tetrahedra. All Li–As bond lengths are 2.64 Å. Nb5+ is bonded to four equivalent As3- atoms to form NbAs4 tetrahedra that share corners with four equivalent NbAs4 tetrahedra and corners with eight equivalent LiAs4 tetrahedra. All Nb–As bond lengths are 2.49 Å. As3- is bonded to two equivalent Li1+ and two equivalent Nb5+ atoms to form corner-sharing AsLi2Nb2 tetrahedra.
