Abstract

Na2FeH8(SO6)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with two equivalent FeO6 octahedra, corners with four equivalent SO4 tetrahedra, and an edgeedge with one NaO6 octahedra. The corner-sharing octahedra tilt angles range from 56–67°. There are a spread of Na–O bond distances ranging from 2.40–2.63 Å. Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with four equivalent NaO6 octahedra and corners with two equivalent SO4 tetrahedra. The corner-sharing octahedra tilt angles range from 56–67°. There are a spread of Fe–O bond distances ranging from 2.12–2.21 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.74 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.72 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å.more »« less
