The structure described by Sr2LiNH2 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent H(2) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent N(1), one H(2), and three equivalent H(1) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to three equivalent N(1), one H(2), and two equivalent H(1) atoms. N(1) is bonded to one Li(1), two equivalent Sr(1), and three equivalent Sr(2) atoms to form NSr5Li octahedra that share corners with four equivalent H(1)Sr5 square pyramids, edges with four equivalent N(1)Sr5Li octahedra, and edges with four equivalent H(1)Sr5 square pyramids. There are two inequivalent H sites. In the first H site, H(1) is bonded to two equivalent Sr(2) and three equivalent Sr(1) atoms to form HSr5 square pyramids that share corners with four equivalent N(1)Sr5Li octahedra, edges with four equivalent N(1)Sr5Li octahedra, and edges with four equivalent H(1)Sr5 square pyramids. The corner-sharing octahedral tilt angles range from 3-11°. In the second H site, H(2) is bonded in a 2-coordinate geometry to two equivalent Li(1), one Sr(1), and one Sr(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
