Materials Data on ZnP2H14C2(NO)6 by Materials Project
ZnP2(HO3)2(CN3H6)2 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional and consists of sixteen guanidinium molecules and one ZnP2(HO3)2 framework. In the ZnP2(HO3)2 framework, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four equivalent PHO3 tetrahedra. There is two shorter (1.97 Å) and two longer (1.98 Å) Zn–O bond length. P5+ is bonded to one H1+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with two equivalent ZnO4 tetrahedra. The P–H bond length is 1.42 Å. There are a spread of P–O bond distances ranging from 1.52–1.56 Å. H1+ is bonded in a single-bond geometry to one P5+ atom. 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 Zn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom.
