Abstract

The crystal structure of zinc metaborate has been determined by single crystal x-ray methods. The crystals have cubic symmetry with a = 7.48±0.01 Å, space group I[unk]3m, and two molecules in the unit cell. A complete set of atomic parameters has been determined by Patterson and electron-density projections and the final parameters have been refined by (FoFc) syntheses. The structure has all boron atoms in four-fold coordination. All these tetrahedra are linked to each other forming a three-dimensional framework. The zinc ion lies inside of a tetrahedron whose corners are occupied by three oxygen atoms of the metaborate ion and a free oxygen atom.
