The compound described by Sr(NH2)2 crystallizes in the tetragonal I4_1/amd space group. Sr(1) is bonded in a 6-coordinate geometry to six equivalent N(1) atoms. N(1) is bonded in a distorted water-like geometry to three equivalent Sr(1) and two equivalent H(1) atoms. H(1) is bonded in a single-bond geometry to one N(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
