Abstract

Mg2Ta4O9 is Ilmenite-like structured and crystallizes in the trigonal P-3c1 space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with nine TaO6 octahedra, edges with three equivalent TaO6 octahedra, and a faceface with one MgO6 octahedra. The corner-sharing octahedra tilt angles range from 48–54°. There are three shorter (1.99 Å) and three longer (2.16 Å) Mg–O bond lengths. There are two inequivalent Ta+3.50+ sites. In the first Ta+3.50+ site, Ta+3.50+ is bonded to six equivalent O2- atoms to form TaO6 octahedra that share corners with three equivalent TaO6 octahedra, corners with six equivalent MgO6 octahedra, edges with three equivalent TaO6 octahedra, and a faceface with one TaO6 octahedra. The corner-sharing octahedra tilt angles range from 48–54°. There are three shorter (2.11 Å) and three longer (2.19 Å) Ta–O bond lengths. In the second Ta+3.50+ site, Ta+3.50+ is bonded to six O2- atoms to form TaO6 octahedra that share corners with three equivalent MgO6 octahedra, corners with six TaO6 octahedra, edges with three equivalent MgO6 octahedra, and a faceface with one TaO6 octahedra. The corner-sharing octahedra tilt angles range from 48–57°. There are three shorter (2.06 Å) and three longermore »« less
