Li4SrN2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a trigonal planar geometry to three equivalent N(1) atoms. In the second Li site, Li(2) is bonded in a linear geometry to two equivalent N(1) atoms. Sr(1) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. N(1) is bonded to two equivalent Li(2), three equivalent Li(1), and two equivalent Sr(1) atoms to form a mixture of distorted edge and corner-sharing NSr2Li5 pentagonal bipyramids.
Li4SrN2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a trigonal planar geometry to three equivalent N(1) atoms. There is one shorter (2.08 Å) and two longer (2.13 Å) Li(1)-N(1) bond lengths. In the second Li site, Li(2) is bonded in a linear geometry to two equivalent N(1) atoms. Both Li(2)-N(1) bond lengths are 1.91 Å. Sr(1) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. There are two shorter (2.64 Å) and two longer (2.65 Å) Sr(1)-N(1) bond lengths. N(1) is bonded to two equivalent Li(2), three equivalent Li(1), and two equivalent Sr(1) atoms to form a mixture of distorted edge and corner-sharing NSr2Li5 pentagonal bipyramids.
