C5N4O3 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four C5N4O3 clusters. There are five inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one O(1) atom. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(3), one N(2), and one N(4) atom. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one N(3) atom. In the fourth C site, C(4) is bonded in a linear geometry to one N(1) and one O(2) atom. In the fifth C site, C(5) is bonded in a linear geometry to one N(4) and one O(3) atom. There are four inequivalent N sites. In the first N site, N(4) is bonded in a bent 120 degrees geometry to one C(2) and one C(5) atom. In the second N site, N(1) is bonded in a bent 150 degrees geometry to one C(1) and one C(4) atom. In the third N site, N(2) is bonded in a bent 120 degrees geometry to one C(1) and one C(2) atom. In the fourth N site, N(3) is bonded in a single-bond geometry to one C(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(4) atom. In the third O site, O(3) is bonded in a single-bond geometry to one C(5) atom.
