Title: Structure of the copper(I) tantalum oxide, Cu/sub 5/Ta/sub 11/O/sub 30/

Abstract

The structure of hexagonal CU/sub 6/Ta/sub 11/O/sub 30/ (space group P62c) has been determined from single-crystal diffractometer data. The cell dimensions are a = 6.2297(2) angstrom and c = 32,550(2) angstrom, and the cell content is two formula units. The structure is related to those of CaTa/sub 4/O/sub 11/ and CeTa/sub 7/O/sub 19/ and contains alternately single and double layers of TaO/sub 7/ pentagonal bipyramids sharing edges in the equatorial plane in the same way as UO/sub 7/ in ..cap alpha..-U/sub 3/O/sub 8/. The layers are connected by TaO/sub 6/ octahedra and linear CuO/sub 2/ groups, both formed by the apex oxygens of the TaO/sub 7/ bipyramids. Refinement was made with the least-squares technique using 729 reflections, of which 422 were independent. The conventional R value was 3.9%.
