Sr(NH2)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four sr (n h2)2 molecules. Sr(1) is bonded in a 2-coordinate geometry to one N(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted water-like geometry to one Sr(1), one H(1), and one H(2) atom. In the second N site, N(2) is bonded in a distorted water-like geometry to one Sr(1), one H(3), and one H(4) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one N(2) atom.
