(Ge7HO16)2(N2)3(O2)4 crystallizes in the cubic P-43m space group. The structure consists of three ammonia atoms and four water atoms inside a Ge7HO16 framework. In the Ge7HO16 framework, there are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to three equivalent O(2) and three equivalent O(3) atoms. H(1) is bonded in a tetrahedral geometry to four equivalent O(3) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a bent 120 degrees geometry to one Ge(1) and one Ge(2) atom. In the second O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Ge(2) and one H(1) atom.
