Abstract

Na3Np(H3O4)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Na3Np(H3O4)2 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with two equivalent NpO6 octahedra and edges with two equivalent NpO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of Na–O bond distances ranging from 2.34–2.64 Å. In the second Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.38–2.54 Å. Np7+ is bonded to six O2- atoms to form NpO6 octahedra that share corners with two equivalent NaO6 octahedra and edges with two equivalent NaO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of Np–O bond distances ranging from 1.91–2.37 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2-more »« less
