The material described by Se(OF)2 is Silicon tetrafluoride-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight Se(OF)2 clusters. In four of the Se(OF)2 clusters, Se(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one F(2), and one F(3) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Se(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Se(1) atom. There are two inequivalent F sites. In the first F site, F(3) is bonded in a single-bond geometry to one Se(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Se(1) atom. In four of the Se(OF)2 clusters, Se(2) is bonded in a tetrahedral geometry to one O(3), one O(4), one F(1), and one F(4) atom. There are two inequivalent O sites. In the first O site, O(3) is bonded in a single-bond geometry to one Se(2) atom. In the second O site, O(4) is bonded in a single-bond geometry to one Se(2) atom. There are two inequivalent F sites. In the first F site, F(4) is bonded in a single-bond geometry to one Se(2) atom. In the second F site, F(1) is bonded in a single-bond geometry to one Se(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
