The crystal structure described by C3H2O4 is Indium-like structured and crystallizes in the tetragonal P4_12_12 space group. The structure is zero-dimensional and consists of four 1,3-dioxolane-4,5-dione molecules. There are two inequivalent C sites. In the first C site, C(1) is bonded in a tetrahedral geometry to two equivalent H(1) and two equivalent O(1) atoms. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one C(1) and one C(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
