Abstract

K4TmP8H12(NO2)8(H2)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional and consists of twenty-four hydrogen molecules and one K4TmP8H12(NO2)8 framework. In the K4TmP8H12(NO2)8 framework, there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to four H+0.89+ and two equivalent O2- atoms to form KH4O2 octahedra that share corners with two equivalent PN2O2 tetrahedra. There are two shorter (2.77 Å) and two longer (2.78 Å) K–H bond lengths. Both K–O bond lengths are 2.62 Å. In the second K1+ site, K1+ is bonded in a 4-coordinate geometry to four H+0.89+ and two equivalent O2- atoms. There are two shorter (2.84 Å) and two longer (3.06 Å) K–H bond lengths. Both K–O bond lengths are 2.72 Å. In the third K1+ site, K1+ is bonded in a 7-coordinate geometry to one N3-, three H+0.89+, and three O2- atoms. The K–N bond length is 3.29 Å. There are a spread of K–H bond distances ranging from 2.97–3.11 Å. There are a spread of K–O bond distances ranging from 2.61–2.85 Å. Tm3+ is bonded in a 8-coordinate geometry to eight O2- atoms.
