Cr2N2O7 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four Cr2N2O7 clusters. Cr(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing CrO4 tetrahedra. N(1) is bonded in a single-bond geometry to one O(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Cr(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cr(1) and one N(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Cr(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms.
