Abstract
The structure determined earlier from x-ray powder diffraction data has been confirmed but changed in detail by new data obtained for a tiny single crystal. Na(1) is displaced 0.4 Å into the large cavity from the center of a ring of six oxygen atoms, resulting in effective three-fold coordination with three oxygen atoms at 2.3 Å and three others at 3.0 Å. Na(2) is displaced 1 Å, nearly in the plane of the ring, from the center of a ring of eight oxygen atoms. The coordination is even more unusual with oxygen atoms at 2.5, 3.0, 3.4, 4.0 and 4.1 Å.Keywords
