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.

Na(1) is bonded in a 7-coordinate geometry to one N(2), four equivalent N(1), and two equivalent H(3) atoms. The Na(1)-N(2) bond length is 2.60 Å. There are two shorter (2.45 Å) and two longer (2.57 Å) Na(1)-N(1) bond lengths. Both Na(1)-H(3) bond lengths are 2.51 Å. Ni(1) is bonded in a rectangular see-saw-like geometry to four equivalent N(1) atoms. All Ni(1)-N(1) bond lengths are 1.92 Å. There are two inequivalent N sites.
