Abstract

MgH4S4(NO4)2(CHF3)2(CF2)2(H2O)4(HF)2(O2)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four difluoromethane molecules, four fluoroform molecules, four hydrofluoric acid molecules, four hydrogen peroxide molecules, eight water molecules, and two MgH4S4(NO4)2 clusters. In each MgH4S4(NO4)2 cluster, Mg2+ is bonded in a distorted linear geometry to two equivalent O2- atoms. Both Mg–O bond lengths are 1.91 Å. N5+ is bonded in a distorted trigonal planar geometry to one H1+, one S, and one O2- atom. The N–H bond length is 1.09 Å. The N–S bond length is 1.69 Å. The N–O bond length is 1.24 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N5+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one S atom. The H–S bond length is 1.34 Å. There are two inequivalent S sites. In the first S site, S is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of S–O bond distances ranging from 1.49–1.57 Å. In the second S site, S is bonded in a 2-coordinate geometry to one N5+, one H1+, and one O2- atom. The S–O bond length is 2.41 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Mg2+ and one S atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two S atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one S atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one N5+ atom.
