Materials Data on PH7CN3O3F by Materials Project
CN3H6PHO3F crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four guanidinium molecules and two PHO3F clusters. In each PHO3F cluster, P5+ is bonded in a tetrahedral geometry to three O2- and one F1- atom. There are a spread of P–O bond distances ranging from 1.50–1.58 Å. The P–F bond length is 1.61 Å. H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.55 Å) H–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. F1- is bonded in a single-bond geometry to one P5+ atom.
