Abstract

Zn4Ta2O9 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Ta5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ta–O bond distances ranging from 1.87–2.25 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to six O2- atoms to form a mixture of distorted edge, face, and corner-sharing ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 46–68°. There are a spread of Zn–O bond distances ranging from 2.01–2.38 Å. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form a mixture of edge, face, and corner-sharing ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 46–48°. There are a spread of Zn–O bond distances ranging from 2.03–2.39 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Ta5+ and two equivalent Zn2+ atoms to form a mixture of distorted edge and corner-sharing OTa2Zn2 tetrahedra. In the second O2- site, O2- is bonded to two equivalent Ta5+ and two equivalent Zn2+ atoms to form a mixture of distorted edge and corner-sharing OTa2Zn2 trigonal pyramids. In the third O2- site, O2- is bonded inmore »« less
