The compound described by Na2Ni(N3H7)2 is Indium-like structured and crystallizes in the tetragonal I4/m space group. The structure is zero-dimensional and consists of two Na2Ni(N3H7)2 clusters. Na(1) is bonded in a 7-coordinate geometry to one N(2), four equivalent N(1), and two equivalent H(3) atoms. Ni(1) is bonded in a rectangular see-saw-like geometry to four equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted water-like geometry to two equivalent Na(1), one Ni(1), one H(3), and one H(4) atom. In the second N site, N(2) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one H(2), and two equivalent H(1) atoms. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one Na(1) and one N(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one N(1) atom. is represented by the CIF card [CIF]
