The material described by SeO3 is Indium-like structured and crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of four SeO3 clusters. Se(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one Se(1) atom. In the second O site, O(3) is bonded in a single-bond geometry to one Se(1) atom. In the third O site, O(1) is bonded in a single-bond geometry to one Se(1) atom. is represented by the CIF file [CIF]
