Figure 1
A perspective view of the asymmetric unit of (I) and the centrosymmetric atoms of the Sn–O framework. Sn and O atoms are plotted with displacement ellipsoids at the 50% probability level; other atoms are shown as small spheres of arbitrary radii. Some of the neophyl groups are shown simply as R for clarity [symmetry code: (i) 2 − x, 2 − y, 1 − z]. |
