(Cr4PO16)2(N2)3 is Indium-derived structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of nine ammonia atoms and three Cr4PO16 clusters. In each Cr4PO16 cluster, there are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form CrO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra. In the second Cr site, Cr(2) is bonded to one O(4) and three equivalent O(5) atoms to form CrO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra. P(1) is bonded to one O(4) and three equivalent O(1) atoms to form PO4 tetrahedra that share  a cornercorner with one Cr(2)O4 tetrahedra and corners with three equivalent Cr(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(3) is bonded in a single-bond geometry to one Cr(1) atom. In the second O site, O(4) is bonded in a linear geometry to one Cr(2) and one P(1) atom. In the third O site, O(5) is bonded in a single-bond geometry to one Cr(2) atom. In the fourth O site, O(1) is bonded in a bent 150 degrees geometry to one Cr(1) and one P(1) atom. In the fifth O site, O(2) is bonded in a single-bond geometry to one Cr(1) atom.
