The material structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
