Materials Data on PHF2 by Materials Project
PHF2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of four difluorophosphine molecules. P3+ is bonded in a 2-coordinate geometry to one H1- and two F1- atoms. The P–H bond length is 1.43 Å. Both P–F bond lengths are 1.62 Å. H1- is bonded in a single-bond geometry to one P3+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one P3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one P3+ atom.
